General Discussion / Re: Newbie Needs some help with a 69 Z 28
« on: April 20, 2018, 01:38:38 AM »
1. Z/28 did not include or require a tachometer until early 1969. At that time it became a required option; either as part of Special Instrumentation which required a console or a new tach only option. The tach only option [U16] immediately had supply problems so for some time Special Instrumentation [U17] and a console [D55] had to be ordered.

William,

How early is early ? My 01C X77 has a console, no tach, no gauges, echoed on the dealer invoice - I always wanted to put the tach and gauges in it, but now leaning towards leaving it like it was and what it is. Shame, I let my factory 6-8 go a few years back, dated January '69 (stupid move, but I needed the cash out of it at the time).

Regards,
Steve

I don't believe the original seal was screwed into the floor - my cable on my Z11 small block looks just like this, apparently replaced at some point, and there are no holes in the tunnel around the seal where an original would have been mounted. I would like to see someone's original cable in place to see what I need to replace it with myself -

Restoration / Re: 69 Z-28 Crank bolt

Kurt,

I considered that before I wrote it. I've learned to shy away from making Definitive statements (no pun intended !).

I did run across this in my parts book - am I misreading the bolt/washer/reinforcement in 0.662 ? I've slept a few years since I rebuilt the 302, I thought I kept these together as I has removed them, but maybe not -

Regards,
Steve

Not blasted yet, but I found my original in the stash, finally.

Star washer is original to this car -

I have one of those TR bolts from a DZ and it had a hole too.  Like bac said safety wired for racing in the day.

If I can find mine, I'll share a pic. TR with the safety wire hole -

Decoding/Numbers / Re: identification
« on: April 04, 2018, 05:03:28 AM »
I saw that another guy got his vin  decoded so I thought my vin might have some info other than the basics.

In addition, your number indicates it was built at the Norwood, Ohio plant. To further pinpoint the build date, it was either the 1st or 2nd week (12A,12B) of December of 1968 and because it does not have an X code, 1st Week is more probable.

You betcha - this car is about 320 cars away from my L78, a 12A car (non-X coded unfortunately). Also, unfortunately, in the middle of the NCRS missing dealer data. At least I have the original engine for a 500 pound P-O-P.

The floor shift automatic in 68 and 69 had no hole for the shifter body itself. It was a plate mounted to the top of the floor...Joe

Correct. One smaller hole for the shift cable through the floor, behind and above the shift lever on the side of the trans.

Look in the technical articles section of Muscle Car Research - I think you can find the solution to your problems. Tuning up the distribution block and metering valve is not too difficult or expensive. The site will also give you a good understanding of what causes what (a lot of us have been through this before).

This, in particular, is the one you should be looking for -

Decoding/Numbers / Re: Need help decoding this cowl tag
« on: March 31, 2018, 04:04:15 PM »
From the CRG 1967 cowl tag decoding link -

"The very first 1967 Z28's and L78's were also coded 4P; the 4L and 4K codes were then used on the remainder of 1967 Z28 and L78 production.

The lack of a 4P, 4L, 4N, or 4K code indicates the car originally had a 327 (assuming the car had a V8, as indicated by the VIN). The only exception is the early SS350's noted above."

Applies to both Los Angeles and Norwood if I read it correctly -

General Discussion / Re: 67 master cylinder
« on: March 31, 2018, 03:54:33 PM »
Assuming the booster is working correctly, look at the end of the old master and determine the depth of the seat for the actuator rod (the piston end) - there are two different lengths, depending on the application/year of the setup ('69's had a shorter rod). If that matches correctly, start chasing the booster, check valve and vacuum source.

My $0.02 -

I haven't ripped-up the carpet to look, but is it safe to assume that there are dimples in the locations for the front console bracket even for non-console cars?


Absolutely. I believe the dimples are in place for the Rivnuts as well - I'll look on my tunnel section I have in storage (non-console) for the rears, but I know beyond doubt the bracket dimples are there, Camaro or 'Bird either way. Had to save a bunch of time on the line to pop the holes in the dimple locations (same for firewall dimples).

Steve

Dave,

  Is that rough cut factory?

Mike
The 4 speed hole? Yes, that's factory cut.

That's a rough one - must have been a Monday after a long weekend, or a Friday in anticipation of a long weekend. I know they were torch cuts, had to have a pattern to trace the outline of the boot retainer (or maybe used the boot retainer as the pattern ?).

Regards,
Steve
