I have a 1970 monte carlo 12 bolt rear, I currently have a 10 bolt non posi rear in my 1968 camaro. Is it possible to install that rearend in the camaro? If so what kind of motifications am I looking at? I realize that they have two different spring systems. If not what is the cheapest or common rear should I put in this car? 1968 nova rear?

Are you looking for a stronger diff or just wanting to add a posi? the monte and the 68 nova housing will be wider o/a.To have them fit right you would need to get them shortened,If your just wanting a posi,maybe just put a eaton unit in your 10 bolt.

The Nova rear will bolt in....the Monte Carlo is too wide

[prostreet6t9]

Poncho is correct, For some reason I was thinking the 68 nova housing was a inch wider that the camaro.

Nope 68 to 72 Nova is the same as 67-69 Camaro.

may have to modify a bit depending if one is a multi leaf rear and the other is a mone leaf...
no huge deal, though...

You can get universal spring pads from Jegs.I had to find a rearend real fast one time and took one out of a 4dr 1971 Chevelle.Cut of old mounts , put on pads using old rearend for measurement purposes.Everything went together fine.I've got a 1970 Nova.Chevelle rearend was a whole 1 inch wider I still had room for my 8" Ralleys and 60 L60-15 tires.I would think the Monte and Chevelle rear would be the same size but I don't know.

The 8.5" rear is nearly as strong as a 12-bolt, and one from a '72-'79 Nova or clone will be the same width, with the spring perches in the same location as yours. '73-up and '72 SS cars will be set up for multi-leaf springs.

You might need to have your driveshaft shortened a little bit, since the U-joint on the 8.5" is a little farther forward of the axle centerline. Try the old shaft first, though, because you might just get lucky.
