Does anyone have Jerry B's ID? I would like to message him about his Chevelle 4.56 gear. Or please ask him to write to me? Thanks.

Some pics for your viewing pleasure....

I have a 1969 Chevelle L78 4 speed originally Butternut yellow. Black top, black interior.
My build sheet has a KM code which matches the stamp on the rear for a 4.56 gear. All the sources I can find on the web point to only one 1969 Chevelle ordered with this rear end ratio. Does anyone else out there have a documented factory 4.56 rear in their car?
Thanks

Hi Mark. I am fairly sure that my 69 Chevelle Sedan Post had factory 4.56 gears. I will have to dig through my albums to see if I still have the GM docs on the car. The only reason I remember is that I was disappointed that someone had changed the gears to a highway set and I had to install the 4.56 gears as I was trying to get the car back to stock. I would be really surprised that it was that rare an option as most guys that ordered an L78 knew the car would not work without a serious gear. I remember that gear was real popular back in the day and 70% of my friends had that gear. If you had a hi revving SBC you could go for 4.88s but with a stock BBC 4.56 was about perfect. I'll get back to you if I find the paperwork. Ken

And you're looking for the VIN for your old 69 Camaro too.

My old 68 chevelle L78 M22 with 4.88 gears was last in Chicago. Any body see it ? Grotto blue. White buckets.

If it was a different speedo gear required because of the rear end ratio, would that have a different transmission code on the build sheet? Are there any other difference between a XF and a XD?
