3931  Camaro Research Group Discussion / Originality / Re: Question of build date vs. rear assembly date on: March 03, 2006, 10:19:54 AM
The "selection" process was simple - the operator looked at the Chassis Broadcast, took his hoist to the rack with those axles, grabbed the next axle in the rack, and loaded it on the chassis carrier; nobody paid any attention to dates. The axle racks came out of the rail car, were stacked in off-line storage, and were taken to the line one rack at a time. Axle racks held four axles each.

Thanks for chimming-in on this John. I was hoping you were on-line.

John, that makes perfect sense. However, how does a rear just "sit around" in a rack
for 4 months before it gets selected. If a rack only held 4 rears, it would stand to reason
that the racks were turned-over on a daily or regular basis. This is the cause for my confusion.

Kurt, by the way, I am referring to a 1970 model.

Who knows - lots of weird things happened occasionally in the production system in those days; that's why the NCRS allows full credit for dated components up to six months prior to the car's final assembly date in Corvette Flight Judging, although 2-6 weeks is "typical".

JohnZ, I notice your Z/28 was built 02D at Norwood as was my L78. My vin is xx5415. Where is your car from mine. About 15 years ago I came across a Z/28 close to where I live that was built 5 cars away from mine.

Loren

Mine is 606402, built a little more than two shifts after yours.

The axle SHAFT itself wasn't painted; the complete axle ASSEMBLY was painted after the drums were installed, as the last operation before the axle was placed in the shipping rack. I don't recall ever seeing any protetctive sleeves on the lug studs, but they avoided painting the pinion flange where the U-joint attached.

They work just fine with the lube they were originally designed, developed, and durability-tested with; ordinary 75W90 or 80W90 gear lube. Don't use a lube that contains a Posi friction-modifier additive - it will slow down the synchronizer action.

Do you have the '69 Pontiac Shop Manual and Firebird Assembly Manual?

Kurt S can probably tell you how that spread compares to other similar cars in the database, but the original 4.10 axle in my 02D '69Z is dated February 19th (the car came off the line on February 27th).

The "selection" process was simple - the operator looked at the Chassis Broadcast, took his hoist to the rack with those axles, grabbed the next axle in the rack, and loaded it on the chassis carrier; nobody paid any attention to dates. The axle racks came out of the rail car, were stacked in off-line storage, and were taken to the line one rack at a time. Axle racks held four axles each.

That's my "driving" setup, with full manifold vacuum (from the tee in the choke pull-off hose, which normally feeds the diverter valve) to the vacuum advance can; for "show", the cap comes off the end of the original steel line, the original short striped hose to the vacuum advance goes back on, the long piece of hose comes off, and the (plugged) diverter valve hose goes back on the choke pull-off tee.

The factory setup used "ported" vacuum to the distributor vacuum advance as an emissions "band-aid" to retard idle spark timing to increase idle exhaust gas temperature to improve the "afterburn" in the exhaust manifolds with A.I.R., but it also caused idle instability, idle and traffic cooling issues, and poor throttle response. Doesn't take much to fix it.  Smiley

The black plastic round choke housing where the wire connections are is adjustable; loosen the three screws that attach it and turn it a notch or two clockwise (rich) and try that; turning it clockwise increases the choke action (and fast idle rpm), and turning it the other way (lean) decreases it.
3939  Camaro Research Group Discussion / Maintenance / Re: 406 small block on: February 28, 2006, 11:45:30 AM
The siamesed-bore 400 small-block was used in many Chevrolets, but was never used in a 1st-Gen Camaro; it didn't become available in full-size passenger cars until 1970. a "406" is a 400 with a .030" overbore.

Most likely there are similar markings on yours - they were applied on the raw metal panel in the Body Shop for options that required additional body-in-white operations over and above those required for a base car.
3941  Camaro Research Group Discussion / Restoration / Re: Chassis and suspension component colors on: February 27, 2006, 10:57:17 AM
Jerry MacNeish's book has an appendix that describes Camaro component finishes in detail; they follow the same pattern as other GM cars of the era.
3942  Camaro Research Group Discussion / Originality / Re: Rally Wheels on: February 27, 2006, 10:52:40 AM
Rally wheels were included in the Z/28 package, and were available separately as RPO ZJ7. Z21 Style Trim was included in the Rally Sport option, and was available separately - it included the rocker blackout (except with dark colors), bright drip rail and wheel opening moldings, quarter louvers, headlight and taillamp accents, and fender and quarter pinstripes.
3943  Camaro Research Group Discussion / Decoding/Numbers / Re: Decode factory wheels for my 69 on: February 27, 2006, 10:43:32 AM
"DC" is a 15" x 6" '67 Corvette rally wheel; was also used on some '67 full-size station wagons; that one is a service replacement made in 1968.  Smiley

Here's the original ZL2 coil mounting on my 02D Z/28.  Smiley
3945  Camaro Research Group Discussion / General Discussion / Re: Rear Seat Removal on: February 22, 2006, 09:56:15 AM
John,

Any tricks involved? I have popped one side loose, but just put my foot through the floor trying to pop the passenger side. Would the build sheet be in any specific area, or "somewhere" on the bottom of the seat? I can pull the drivers side up part way, and don't see anything there. I would love to know what I have.

Thanks!

Tom

Nope, no tricks involved - just push the bottom of the seat frame rearward and up at the same time and it'll pop loose from the "hook" on the floor. Highly unlikely you'll find any paperwork under the rear seat.
