I have found, I think, that my rear axle is not original. I have a 1968 model but the code on the axle is AM with these numbers stamped on the bottom. 11 24 64. Is that the assembly date? Is it a 65 model year axle? Ratio?

Thanks

Don't even think most people want to touch your topic, if you get my drift :jester :p:

If you get in front of one of those full length mirrors and turn your body half way around you should be able to ID your own rear end. :lolg:

Sorry, you were probably hoping someone with some real intelligence would respond...as I'm sure they will. :cheers:

a 68 vette with a 65 differential? it could have any old gears in there! perhaps the easiest way short of disassembly, is to jack it up put a chalk line on the driveshaft and one on the tire, give the tire a spin and count the revolutions of the driveshaft.

Are you trying to say you have a old rear end? :D :D :D

Actually I know the ratio it a 3.35 posi. What I want to know is if that date means its a 65 model part??????? If not what do I look for to identify the year.

chadman, your diff is a posi 3.36 for a 65 manual tranny.

The AM is for 3.36 It should be like AM0621W where 06 = June and 21 = 21st day.. Find that and match to other numbers for full year. Both 1965 and 1968 used the same code....
