WHAT IS THE DIFFRENCE IN THE REAR AXLES OTHER THEN MULTI LEAF, FROM THE 67-69 REAR AXLES TO THE 70 12 BOLT. I HAVE A 70 CAMARO and trying to find a 12 bolt for my car. and does anyone have the right code or know what i am looking for to id it correctly
mike

sorry about the caps at the start....

The 1st gen rears are about 2" narrower than the 2nd gen rears and the spring perches are on different centers.

is it possible to relocate the perches to make this bolt in
im clueless to this any help would be great

The 1st gen 12 bolt is going to cost you more than a 2nd gen 12 bolt unless you have one already. Putting in a shorter assembly will mean replacing your wheels or adding space adapters to make up for the difference along with having the perches moved.

It would be a lot easier for you to use an 8.5" rear end, very common in the 2nd gens and about as strong as a 12-bolt.

The '67 to '69 Camaro rear ends are 60 inches wide over all and the spring perches are 42 1/2 inches apart center to center. The '70 to '81 Camaro rear ends are 61 inches wide over all and the spring perches are 45 1/4 inches apart center to center. You might want to consider a new Moser 12 bolt. The '70 12 bolt is very hard to find because it was one year only. You also might consider the 8.5 10 bolt. It can be built very strong with the right parts. It can be found in '71 to '81 Camaros and Firebirds. You can look at www.nastyz28.com for more information on the '70 to '81 Camaros.
