Will a 1974 to 78 camaro rear end bolt in correctly in place of my original rear end on 53 gmc, Thank you
No ; You'll have to modify (weld) the spring perchaes . Read Russ' most excellent how to build an AD carefully .
Is it a 3/4 or a 1/2 ton? I only ask because a 1/2 ton will have the axle above the spring, and on a 3/4, it will be under the spring. It makes a difference as to where you weld the perch. BTW, there is this neat little piece you can use at that time that will center the back wheels in the fenders, if that offset bothers you.
Cut off all mounts from the Camaro....I'm about to do this at the shop on a 2001 Mustang rear end for the Ford We are building. Now smooth the rearend tbes. Order a set of 3" axle saddle mounts....I got some from Speedway. Set the mounts on the leaf springs, then set the axle in on top of them. Measure to make shure the axle is centered, then measure again. Now set the pinion angle to match the transmission angle, I usually add 2degrees upward to make it push the rear up instead of squatting when loading. When you are shure it is right, tack the saddle brackets to the axle, then take it out and fully weld the mounts to the tubes. Re install axle, use NEW U bolts, torque them down and you are done.
