I would revisit this topic I originally posted it back in 2008.
Since 2008, CRG has added a section dedicated to original and unrestored Camaros so hopefully feedback from the owners of those Camaro can comment and hopefully show photos!
With your feedback we need to know the plant and build date of your car. Your VIN will also help more closely determine when the change took place.
Question: Is it known when the center rear axle bumper changed from the push in style to the bolted in style on the ‘69?
I saw in the ‘69 AIM, section 4, page 59 assembly manual, an engineering change dated 8-29-68, where the center bumper changed from the push in style 3923564to the bolt on style 3962763.
My July 1969 GM Parts Catalog, “Group 5.395 Bumper, Rear Axle Pinion,” calls for screw in type 3962763 for “1969/ALL” along with this note: “When used in place of a push in CN bumper it will necessary to drill two 9/32 holes, using bumper as a template, and attach with 5/16-18 tap screws.” It also calls for screw 3958062 which is a self tapping screw.
When I posted on this question on CRG back in 2008, I got two responses. An 04C ‘69 had a push in style, my 45k mile 05A Norwood build N639712 ‘69 had the original push in style still on the car when I started my restoration. One other ‘69 Camaro owner responded with a ‘69 June car from Van Nuys had the bolt in style. I recently discovered on CRG the low mileage LeMans Blue X77 Z28 survivor, late build 10E Norwood car had the screw in center axle bumper.
All told, based on the GM documentation dates and this very small (4) sampling of ‘69s, it appears the change phased in between mid-May and June 1969.
Can anyone with an unrestored survivor, or documented original restored ‘69, share on this topic?
The photo attached is from the 10E blue survivor.
I’ll start photo documenting this anytime a see a ‘69 survivor!
Happy New Years!
