I think I read some where that GM was putting out 600 Camaros a day???

912 per day from Norwood, and 280 per day from Van Nuys = 1192 per day.

Not possible. Clearly a restamp. No DZ engines were built at Tonawanda.
33  Camaro Research Group Discussion / Mild Modifications / Re: Hub Centric Adapters on: December 27, 2014, 11:43:01 AM
I read the earlier thread about mounting Torque Thrust II's on a 67 z/28 but no source for adapters was given. I my case I have a 69 Z with TTII's made in the mid 90's. I've tried the use of conical lug nuts to achieve a better concentric fit and then switch over to the long necked lug nuts but it's quite hard to repeat that successfully. I've contacted numerous Wheel/Tire stores but no one (not even American Racing) offers concentric adapters for my wheels and car. My measurements indicate a 70.5mm ID with a 85.5mm OD and .25inch thick would be good. It seems that I'll have to have custom ones made, but before I do that I thought I'd ask this august body for any other suggestions. BTW, the tires and wheels have been professionally balanced and checked for roundness and that helped but just not enough. Up to 60 mph all is ok, but after that the vibration get's obnoxious. I also tried original YH wheels that when installed work perfectly. Thanks.  Smiley

Tires can be perfectly balanced and still cause vibration, also known as "smooth road shake" due to tire construction variables that don't show until the tire is loaded with vehicle weight.

Find a shop/dealer with a Hunter GSP-9700 Road Force Balancer (go to and use the locator feature - there's one near you) and have them check out your wheels/tires - it checks both lateral and radial runout, balance, and response to full road force load at speed, and its diagnostics show the operator how to optimize it by moving the tire on the rim.

Use of adapters/spacers is a BAD idea. Use the lug nuts the wheels were designed for.

Are you saying the argent silver paint should be 'semi-gloss'?   

I thought argent silver paint is standard gloss... but of course, not buffed or polished so the wheels might appear to be 'semi gloss' in finish...

Yes - the argent silver is certainly not "glossy" - it was just ordinary wheel enamel; see page 206 in the finish specs appendix in Jerry's book.

<< I want to pick up the paint for my ralley rims that I'm going to paint. I'm not sure about the finishes, should the back be a semi gloss Black and the front a semi-gloss Argent Silver ? >>

Yes - see photos below of the back of an untouched original rally wheel, with small foggy areas of silver overspray that came through the slots when the face of the wheel was painted.

So in 67 did they still have the option for the spinners?

No, they didn't. One of the first MVSS (Motor Vehicle Safety Standards) regulations in 1966 (sponsored by activist Ralph Nader) banned "winged projections" on wheels or wheel covers, as he felt that it constituted a hazard to pedestrians.

BTW, no true Corvette knock-off wheel ever came off if it was installed correctly; people didn't read the instructions or let tire shops who didn't have a clue take them off and put them back on, and that caused problems.

After 1967, sets of Corvette knocik-off wheels sold over the parts counter came with large hex nuts instead of 3-eared spinners, and a box-end wrench to whack with the knock-off hammer - see photo below.

The N89 wheels alone are worth $15K.   Angry

<< Do RS's come with standard? I have only seen Deluxe. >>

Standard interior came on every Camaro unless the customer ordered an optional Deluxe interior..

<< Are you saying that they are not orig? >>

I don't know, but every Kelsey-Hayes wheel I've ever seen has the size, month and year date, K-H logo, and Tire & Rim Association certification logo stamped on the inside, under the tire.
40  Camaro Research Group Discussion / Decoding/Numbers / Re: Rally wheel dating on: December 23, 2014, 02:37:30 PM

I've never seen a 67 model year DG wheel with a year stamp of 66, so I'm wondering if they just started that year & month stamp in January 1967?


Kelsey-Hayes has been stamping the wheel size and month and year date code on the inside of the rim since 1951; Chevrolet wheels didn't get the type code and dating stamped on the outside of the rim adjacent to the valve stem until 1968.

John Z as a young foreman working the line what was your first impression of this ( '67-'69 ) new pony car called Camaro? Did you owned one at the time or was it just another car? I know the bigger car were popular back then and did you know about the COPO 427 '69 camaro's then? I like the first person history.

Those of us at Willow Run were introduced to the new Camaro first-hand, as the first 1,100 Norwood Camaros were shipped to Willow Run to have the steering linkages changed; there had been a heat-treat process failure at Chevrolet-Buffalo (where the steering linkages were made), and it wasn't found and contained until 1,100 cars had been built.

We shut down production at Willow Run, cleaned out the Final Process Repair Department on a Friday, and converted the two light mechanical repair lines on Saturday to a disassembly line to remove the steering linkage, and an assembly line to install the new certified-OK linkages from Buffalo, re-roll-tested and re-set toe-in, re-shipped the Camaros to their original destinations, and resumed normal production on Monday. On Saturday we burned-up every pitman arm puller in the plant, bought every one we could find at every auto parts store in Ypsilanti, and got the President of Kent-Moore (GM's Service Tool supplier) out of bed Friday night to get every pitman arm puller they had in their warehouse to Willow Run.

That exercise gave us a first-hand look at the new Camaro; in those days they scheduled the plain-Jane low-option cars first and introduced complexity gradually as they ramped-up, so we saw mostly six-cylinder cars, bench seats, and manual transmissions (three on the tree).

At that time my personal cars were a '65 Tri-Power GTO and a '65 Corvette; I later sold the GTO and bought a new '67 Impala SS427 from the Engineering Fleet.

I have a set of door mirrors for a 1969 Camaro I would like to have restored because they are "Originals".

What is a "set"?  1969 Camaros only had one door mirror, on the driver's side.
43  Camaro Research Group Discussion / Originality / Re: Correct Dip stick on: December 20, 2014, 11:16:58 AM
The measurements in the P&A are taken from the seal surface facing the stick end. The problem is that the stick shown is generic in that it has a washer and a seal and no bell.
Stop the press. Just found something interesting in my 67 Corvette AIM that may explain the purple button.

'67 Corvette big-blocks had dipsticks with pink (salmon) buttons, both before and after the mid-season running change.
44  Camaro Research Group Discussion / Decoding/Numbers / Re: Intake Date Code on: December 20, 2014, 11:10:51 AM
How about  intake # 3933163 date 3-29-68 on a motor # 3935440 date G 1 8  L.A. 69 car ?

G 1 8 is the block casting date - what matters is the engine assembly date.
45  Camaro Research Group Discussion / General Discussion / Re: 67 Camaro Pilot Line Assembly Process and Procedures on: December 20, 2014, 11:04:10 AM
   But did you solve the problem?

Absolutely! See the end of the second paragraph in that post:

<<I described to him the line-stop problem that caused, and asked if he could wipe off his brush elsewhere. He understood, and said he could do that, no problem. I thanked him, and headed back toward the Chevrolet side, pleased that I had solved this apparently unsolvable problem with ten minutes' work.>>
