Looks like a 20 to me. But those ears on the chunk say "G" body.

I don't see any diff cover bolts.
Any even halfway modern rear drive coil spring GM car is going to have those upper control arm "ears", that narrows it down to what, 1964-2002 cars? Not very precise.

That rear cover, along with that "truss" running under the center section, will give that axle away to someone who knows what it is. The upper control arm ears are pretty much pointless, that is a generic feature for most coil sprung rear axle cars, regardless of make.
Yeah, that's the closest I can get but Dyeager says, the ears and truss would identify it to someone. I've spent hours searching but still can't find a match. I don't think the m20 has that truss thing either, but I've not had the opportunity to get under one and look for myself.daleearnhardt01 said:Yeah I think its the AMC 20... looks like the one under my buddies CJ5

I've only seen these with 10 cover bolts. Got any links or photos?pauly383 said:As for the Camaro rearend , it looks like an old A-body 10 bolt , NON Chevy style . They had 12 bolt covers , the trailing arm ears like any other A-body , and 10 bolt ring gears

Yeah, kinda spooky and really frustrating!!pauly383 said:Looks like someone did some weird voodoo there . I see 3 ring gear bolts , now mirrior that and add one top and one bottom , you have 8 .
Looks like a model 20 the more ya look at it internally .
