Speedometer drive adapters

**scuncio** · #1 03-31-2011, 03:19 PM

I have two of the 90 degree AC speedometer adapters and was wondering if either is correct for my 1968 Z/28 with 4.56 gears. The first is 6478879 (1:.882) and the other is 6477965 (1:.833).

Thanks,
Tony

I believe the .833 is the same used in the Deuces which have an M21 and 4.10 gears. Not sure about the .882 though.

Yes - the .833 is correct for a close ratio Muncie and 4.10 rear gears.

I think I still have it. Send me a private message and I'll look around for it. Thanks, Tony
