need 1969 Los Angeles Z28 expert...
« on: April 13, 2018, 03:15:30 AM »
I am looking for a respected Z28 Camaro authority to verify and authenticate a 1969 Z28 made in Van Nuys, Ca plant.  I have a complete trail with names, phone numbers, etc of those who knew the car, a history of all of the owners from new.  This is a documented Vintage SCCA Road Race car, that the third owner I bought it from was told was not a Z28.  But the rear differential and original owner's family say was one.  Of course it does not have the X code on the trim tag.  It was made Feb 3, 1969, shipped to Paso Robles, CA.

I have photos of the original rear end numbers, stampings (and access to it out of the car).  I have the documentation and done the hard work, now need someone to make expert decision and provide proof it was originally a Z28 besides me.

Who would I go to for this?  The car is in Des Moines, IA.

Thanks for any help guys!

You're asking for the impossible. As a vintage race car, all originality has been destroyed. The presence of a BU axle isn't worth much as there is no VIN stamp on them. A 3.73 positraction axle was also available on Camaro SS along with a Muncie 4-speed trans and dual exhaust.

Without genuine, factory original paperwork there is no way of knowing the original build configuration of the car.

... My (old) memory is beginning to wake up...  Didn't you come on this website about 10 yrs ago, basically asking the same questions?  I think we talked on the phone at that time...  I haven't seen you at the NCM in even more years than that...  :)

Dan, are there more clues than just the rear axle housing stamp? I suggested Jerry M as I thought from the wording of your question there was more evidence on the car or in the documentation to assess it.....
Now based on Gary's comment above, I had a look at your older posts and it sounds as though you found evidence during disassembly that the car was originally a 396 with C60?

   Yes, years ago, I posted we figured out it was a 396.  The co-owner of the Camaro told me the guy he bought it from told him it was not a Z28.  Taking his word for it, the only other combination would have had to of been a 396 SS Camaro.  That was then.  But, when I found photos of when it was a street car and wrecked, it had a Z28 badge on the driver's front fender.  I had known it was made in Van Nuys, but had no idea why it ended up in Iowa.  The article in the paper told the original owner's name, and that it was a Z28.   Then I contacted the first owner's family after finding their names in his obituary.  One by one, they all said it was a Z28.  So how does an Iowa Dealer think it is NOT a Z28?  I can only guess the trim tax does not have an X code on it, so he thought it was NOT a Z28.  The Co- owner still swears it is not one.  So I was hoping for someone I could get to clear this up.  I have copies of the newspaper article, names, contact info, notes on what they said, and part numbers off the Camaro.  I have the complete owner history now, all 4 owners.  But if you guys can't help, that is OK.  Just trying to do the right thing, and thought I could get someone to help me.  I wish I could correct my old posts, but water under the bridge.  I know a lot more now.
Thanks, Dan

What's the axle code?
3.   REAR AXLE- (original) assembled January 20, 1969: All Z28 had 12 bolt rear ends.
12 bolt, 8.875”
Stamp codes on tube= BU 0120G1
                                                 E
Decodes as BU- originally a 3:73 gear (BV was a 4:10), with posi, 12 bolt for 1969.
01= January, 20= 20th day, G= Detroit Gear and Axle plant, 1= 1st shift, E= Eaton posi unit.  BU was the normal rear end ratio recommended for the Z28.  Doug Walker had the gears changed to 4:10 after he bought it.

Axle Housing casting(original) cast Jan 3, 1969:  The photos of the housing show the following casted in numbers:
•   Test numbers- 12345 
•   Test numbers- 67890
•   Part # 3894860NF= 12 bolt casting #.
•   GM58= GM Model number of differential
•   CON1= casting foundry conveyor #.
•   Date:  A39= decoded as a= January.  3= 3rd day of month.  9= 1969 year cast.
Axle posi-traction unit (internal) is original but had new clutches in it. 
Axle Gears (internal):  Not original:  The axle has 4:10 gears in it by manually counting turns. The clutches in the posi-unit were replaced in 1982 by a performance shop in Ankeny, and Laverty changed the axle gears from 3:73 to the current 4:10 in it now.

Dan,  If you wanted to include your new information to correct the 'record', then I'd suggest you go find your old posting, and QUOTE it, and then add the updated/corrected information...  that would put all your info in ONE place and help anyone in the future digging into the car's history...  I'd suggest PUTTING all the info you have into the post... including owners/cities/etc...

PS.  Are you planning to 'restoring' the car (as close as you can) to it's original configuration??

PPS:  EDIT:   After I posted the above, I found that you had already *(updated)* your previous post!!

Good luck,

Gary
