Originality / Re: D55 Console with U17 Gauge Package (pic heavy)

<<You need a potentiometer capable of zero to 100 Ohm's >>

I made this tool to calibrate Corvette fuel gauges - it's a 0-100 ohm Radio Shack variable potentiometer with a pair of clip leads soldered to it; I mark the potentiometer shaft and body from readings on a VOM, then compare gauge needle deflection at several points along its variable resistance curve.  :)

Anyone know if Flint Engine assembly ran 7 days, night and day?

Flint V-8 normally ran two 9-hour Assembly shifts, 5 days a week, plus two overtime shifts every other Saturday. Every day Assembly ran two shifts, Machining ran three 8-hour shifts.

In Assembly, Line #1 ran at 170 per hour, and Line #2 ran at 130 per hour; the combined output (300 per hour, one engine every 12 seconds) generated about 2700 engines per day. Flint V-8 didn't operate on Sundays.

Originality / Re: Compressor inspection stamp?
« on: March 08, 2017, 12:22:13 AM »
'Needing help in recreating the '67 A/C inspection stamp that was placed on the A6 compressors (Norwood built, 11B).  When cleaning years worth of repaints from the compressor, I uncovered a partial inspection stamp that I believe inspectors placed on the compressor when the A/C system was tested and certified.

The partial stamp is a yellow circle which is approximately 1-1/8" round, has "TEST" inside the circle, and has "CHEV" outside the circle at 6 o'clock.  I believe that the stamp was placed half on, and half off,  the compressor ID sticker.  Anyone have a photo or the actual wording inside the circle?

Thanks for your help!

Steve


In '66-'67, that was a paint/ink pad stamp, applied after final compressor test at Frsigidaire - most of the Corvette resto houses (Paragon, Long Island, etc.) have the stamps.

Would the plastic dash be different for one with a clock verses one without a clock? In other words were there two different dashes depending if you had a clock or not?

The hole for the clock or the tach was die-pierced in a hydrauiic fixture in the assembly plant, on the dash cluster subassembly line.

General Discussion / Re: Chassis Broadcast Sheet

There's another possible aspect to the "Broadcast Copy under the rear seat story" , but not on first-gen NOR cars. Norwood was an old Fisher/Chevrolet plant, and followed the same overall sequence as all the other Fisher/Chevrolet plants, where Fisher supplied a painted and trimmed firewall-back body shell to Chevrolet and Chevrolet made a car out of it.

GMAD plants, however, weren't constrained by Fisher traditions, and used the "soft trim after Final" sequence, where all of the interior soft trim parts were installed AFTER roll-test and water-test as a driveable car (Corvette also followed that sequence); easier to spot water leaks and no water damage to costly interior parts. At some point after GMAD absorbed Norwood (don't recall when offhand), Norwood changed to the GMAD sequence, and that system would have made it possible to find a Broadcast Sheet under the rear seat.

Does anyone know anything about John's recovery?

John has shown remarkable improvement over the last few months and was discharged from the Hospice facility last Wednesday (02-15-17). He's now home and I'm sure he'll be checking in shortly.

Hi, guys, and you all have my deep appreciation for your thoughts and prayers - that has to be what turned this medical nightmare around, I'm sure. It sure feels good to be back among the living - I came perilously close to the other side in December, after 14 weeks of five separate middle-of-the-night screaming ambulance rides to Emergency admissions for gastrointestinal, heart, lung, and kidney failures (singly, and in combination), only four days at home in 4 months, professional in-patient rehab following hospital discharges, and 8 weeks of in-patient Hospice treatment after the doctors gave up.

Got to me for a while, then I decided it was MY decision, and with the emotional support of the Hospice folks, your thoughts and prayers, and the continuing positive encouragement of my wife Linda and many of my closest friends, about the third week of Hospice my health took a dramatic upturn, I walked for the first time since everything went downhill in early September, the "crisis" in my medical condition faded, and things continued to improve, to the point that I left the outside Hospice facility last Wednesday, standing up and walking.

I'm on oxygen 24/7 (concentrators in the house and in the garage office with nasal cannulas - no bottles) and my new buddy-for-life urinary catheter (Foley) in addition to my insulin regimen as a diabetic. There are about 14 other things that aren't working right either, but I'm sticking with what we're doing - it's working. (-:

It's great to be back! I'm glad I built this garage 48' deep 16 years ago - the new 44'-long ramp up to the door to the kitchen works out just fine. Even Max the dog figured it out!  :-)

You stated that the master cylinder was sleeved, what's the status of the brake hoses and lines?

The brake flex hoses (safety item) were replaced ten years ago, lines were nicely protected by the original dealer-installed undercoating (very common on Canadian-delivered cars of that era).

JohnZ may know him....

Nope, doesn't ring any bells with me.

These pics show the cowl tag, the green "T" below it, the acorn nuts on the rearward rear spoiler attachments and the stud-and-sealer nuts on the forward rear spoiler attachments. This car was built about two weeks before the "short" rear spoiler disappeared.

Always great to see pics of your car John.   John was very helpful to me several times during the resto of my 10 10 Z/28.   I am wondering if the original owner had the cowl area touched up when he did the other touch up.   Mine had a lot of white (stirpe color) paint on top of the cowl, with some overspray on the firewall.  I notice yours is body color instead of stripe color.  I also realize our cars are almost 6 mos. apart, and that the procedure could have changed over time.

I have some pics of what it looked like originally somewhere.   I also have a pic of how I replicated it during the resto.

Thanks again for all you do for this hobby.

Lynn -

I'm sure the original owner did or had some touch-up done to cover the white stripe overspray typically seen in the open cowl area, as there is none visible.

Even though he wasn't at the Muncie plant, I would have to let John comment on this. He may have inside information.

Sorry, can't shed any light on this; many others (like Jerry and "Crash") are much more knowledgeable than I am with those details.

Beautiful car for sure!  It's so nice to be able to see these rare unmolested cars after all the years that have passed.
I'm trying to study some of these option packages and learn the details of them.  Since this car is an X33, it has the Z21 style trim option (I think).
Are the door edge guards somehow part of that?, or a separate option?, or maybe just a dealer add-on?
Also from what I gather the Z21 should have the rear quarter louver accents and it looks like maybe this car doesn't have them?  The side view wasn't direct, so I may not be seeing them.

Help a newbie out! :)
 
p

See reply #2 on page 1 of this thread, which explains why the quarter panel louvers (and the Camaro nameplate on the fender) are missing; the quarter louvers are part of Z21, which is part of every X33 car. The door edge guards were part of the Appearance Guard Group, and could be ordered separately (as they were on this car) as RPO B93.

<<Wow! Great find, beautiful car! Ours were 530 apart on the line, and our brithdays are a day apart, too. Would love a couple pics of the lap belts (as bolted to the floor next to the console). Mine now have a twist (when worn) that I don't believe was there pre-restoration.>>

Photo below is the driver's side lap belt stack, which has never been touched - I haven't noted any "twist"

Everybody wants real sill plates with the riveted-on Fisher Body emblems, but you only find that on assembly-line parts; these are originals. The RC-15 radiator cap is original, and still seals 15 psi with no problem.

The door latches show the paint process (latches installed in the Body Shop), and you do NOT want to try and remove the door edge guards from 47-year-old lacquer. The 5045572 wiper motor, dated "036 9 B F" [February 5th, 1969] is original.
