1969 L78 4:56 gear
Hello, new member here, I've been reading the forum for a while and just joined.
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 |
Wow, I’m no Chevelle expert, but I’m anxious to hear about this question.

There was a Black '69 Hardtop factory 4:56 car we looked a here a few years back. Factory 4:56 is special as some info indicates Copo 9511 was necessary for '69 model cars. Looking forward to seeing/hearing more about your car, welcome aboard! :beers: ~ Pete . |
Jerry B. Garnet Red '69 L-78 Chevelle has a factory 4.56 rear....not a COPO.

Yep and Jerry has the build sheet on his car.

The build sheet has a XF code crossed out and XD written in. Seems strange that they would replace an M21 with another M21 code. A friend suggested to me that perhaps it was meant to be replaced with a M22. The transmission is in the car, so I haven't been able to verify the shaft or the angle on the gearing to confirm it as an M21 or M22.
I have not driven it yet which would make it much easier to tell which trans. Unfortunately, it no longer has the original motor. The sheet metal appears to be all original and in great shape. Surprisingly for a NJ car, it has original quarters rockers and fenders. Floors and trunk are also very good. I'll post some pictures soon. |
Welcome to this site and I'll look forward to seeing pictures and hearing more about your L78.
