I have a 67 camaro with a 10 bolt non-posi 2.73 rear-end. My ? is, is there any doner car that I can get with a 12 bolt posi 3.73 rear-end with multi-leaf suspention that will bolt on or without difficult mods?

I also want a 700R4 is there a car that I can get both from maybe newer like 88-92?

Thanks in advance for any advice.

I believe GM stopped putting 12 bolts in cars in the early seventies.

68SS ZZ4, 4sp T-10, 12 bolt, getting painted

78Z28, 330hp vortec, TH350, 10 bolt (just finished)

12 bolt rear ends were only made from '65 to '72. The only ones with multi leaf springs that will fit your car are the '68/'69 camaro rears. The '67 camaros all had mono leafs. Can't help you with the 700R4.

what about birds, did they come with 12's

i think so, but pontiac was different. I'm pretty sure of this cause my uncle has both

Nova's from 68-70 could come with 12 bolts (SS's inparticular), maybe even 71 or 72. Good luck finding any 12 bolt, they are very hard to find.

67-69 camaros,68 through (72-74 10 bolt) novas will fit.I believe the nova rear is a little narrower but only by an 1". Don't quote me on the size.

8.5"10 bolts ars stronger than people give them credit.

don't overlook the late model 8.5" 10 bolts. They're almost as strong as a 12 bolt, plentiful, cheap, and more likely to have posi. Take a tape measure and shop the junkyards. It doesn't cost much to have spring perches welded on, so just look for the correct width.

Sorry, forgot about the nova rears.

Yes.

I have the same lousy rearend in my 68 camaro. What all would be needed to change the guts to make it a 3:73 posi?

You would need to get a posi carrier and the gears you want. I think Eaton and someone else makes carriers. While you are in there you might as well replace all the bearings and seals. The best thing to do would be find a competent rear end shop and discuss with them what you want.
