That is a plant scheduling code used only at Van Nuys; has nothing to do with the configuration of the vehicle. The code is alpha-numeric so it is merely a coincidence that yours has a Z. The next day probably started back at A001.

1115  Camaro Research Group Discussion / General Discussion / Re: 69 Camaro metal dash replacement - will Nova work? on: April 27, 2006, 06:34:06 PM
69-78 X-body [Nova, Pontiac Phoenix, etc] did use the same basic dash structure as the Camaro but it does differ where the instrument cluster is located. The Camaro dash has some punched holes with welded bracketry along the right side of the opening, the Nova dash does not. The speaker grille also has a slightly different configuration.

E70 x 14 tires were never available as original equipment on a 1969 Camaro.

The standard size [non-SS or Z/28] was E78 x 14; F70 x 14 optional.

SS cars had F70 x 14 as the standard size; several varieties were optional.

Z/28s and COPOs also equipped with 9737 used E70 x 15. There were no 15" tire options.
1117  Camaro Research Group Discussion / Originality / Re: 1969 spare wheel on: April 19, 2006, 10:01:11 PM
All 5 wheel/tire assemblies matched unless the car was ordered with N65 space-saver spare, available only with 14" wheels.
1118  Camaro Research Group Discussion / Restoration / Re: 69 Z28 engine dates on: April 18, 2006, 12:27:04 PM
I have around 400 '69 Z/28 VIN/engine dates in my db. For the most part none of the rules apply to Z/28s.

A couple of factors are which plant assembled the car and when it was assembled.

Here is something to consider: There is paperwork showing a 2nd week February Z/28 was built with a 2nd week February engine. The car was delivered to the original owner exactly 1 week after the engine was assembled.

Our documented 06E '67 Z/28 had an engine built July 6th. Go figure.

Don't apply this to SHP big blocks; they defy logic. COPOs built within minutes of each other can have engine dates 5 weeks apart.

Check for BB crossmember. Should have SB. Creates a different alignment problem.
1120  Camaro Research Group Discussion / General Discussion / Re: 69 RS/SS L78 on: April 13, 2006, 08:59:16 PM
There were 34,922 Camaro SS built.

There were 37,773 Camaro RS built.

4,886 Camaro SS had the L78 engine.

How many had all three options is anyones guess. Chevrolet never furnished that info.
1121  Camaro Research Group Discussion / Originality / Re: 1969 350-300hp with 140-speedo..7k tach..? Help on: April 13, 2006, 12:51:41 PM
Almost certainly a repro 140. It has been available for some time.

The only known factory application for the 140 was COPO 9737 which also included 15" x 7" rally wheels with E70 x 15 tires and a 13/16" front stabilizer bar. It is believed 9737 was only available when COPO 9560 or 9561 was also ordered. The 5000 RPM red line 7000 RPM tach was supplied when a tachometer or special instrumentation was ordered with the 307, 327 or 350 engines.
1122  Camaro Research Group Discussion / Maintenance / Re: 69 Z/28 engine stands on: April 12, 2006, 12:11:09 PM
A couple of other signs you have the wrong mounts are the balancer very close to the stabilizer bar and the #5 spark plug right next to the PS gear.

The mounts have changed #s over the years. You need 69 302/350 or 69 396/427 mounts, same thing.

I learned this the hard way 30 years ago with a 69 Z/28.
1123  Camaro Research Group Discussion / Maintenance / Re: 69 Z/28 engine stands on: April 11, 2006, 12:25:04 PM
Hoo boy.

For 1969 Chevrolet used 2 sets of frame brackets and corresponding motor mount for small-block engines: 327 & 307 use the 67-68 small block brackets and non-interlock mount, 302 & 350 used frame brackets designed for the new interlock motor mount. The 302/350 brackets are shorter and narrower than the 67-68 brackets. The '69 interlock motor mount will not fit on the 67-68 frame bracket but the non-interlock mount will unfortunately fit [loosely] on the 69 frame brackets. If you do this expect clutch chatter and driveline vibration, the engine will be about 1" too low in the chassis.

Complicating the issue is the fact that service replacement 67-68 style motor mounts now have the interlocking feature. The best way to figure out what mount you need is to measure the width of the frame brackets and get motor mounts that are the same inside width-the correct mount is a tight fit on the stand. The 67-68 mount is about 1/4" wider than the 69 interlock frame bracket.

For the record SB & BB do share motor mounts but not frame brackets.
1124  Camaro Research Group Discussion / Restoration / Re: What options came with the Z21 style trim group? on: April 09, 2006, 10:45:46 AM
To further complicate the issue Z10 & Z11s had orange Z/28 style stripes and D96 pinstripes, but not black rockers.

How they got all the trim/stripe/option color permutations straight on the line is a mystery to me. The only error I know of was ZL1 #59: black pin stripes on one side, white on the other.
1125  Camaro Research Group Discussion / Restoration / Re: What options came with the Z21 style trim group? on: April 08, 2006, 12:52:53 PM
Mostly correct.

All '69s had the "lower rocker molding", style trim or not. Obviously convertibles did not have the drip rails. Z21 also included bright vertical trim on the tali lamps. Colors 51, 57, 61, 67 did not receive black rockers. The D96 pin stripes could be ordered on a car w/o style trim. If a car was ordered with Z21 and an optional stripe [D90, DX1] the pin stripes would not be applied.

RS included style trim. SS included some of the style trim features.
