I think the 68-72s are wider than the older A bodies by about an inch. Is this about right?

 

[floyd66]

exactly right!

Do they bolt in? as in I can shorten my rear by an inch by changing to a 66-67 rear?

Bolt right up. You need to use the upper arms from your 68-72 car. The lower arms are the same.

Oh yeah, one other thing. Your wallet may not like the price if you are looking for a 65-67 12 Bolt.

Why wont the upper arms cross over? I've got a 68 12 bolt I want to install in my 66 elco, do I need the uppers from a 68-72?

Glad I read this thread if so! Sorry for the hi-jack, but seems like you might have the same issue.

Thanks,

Brian

Not sure about El Caminos, but the length of the Upper arms is different on the 65-67 Chevelles. I believe the 68-72 Upper arms are longer.

Use the uppers from whatever car you're bolting into. If you're installing the rear into a 68, use the 68 uppers. The mounting points on the diff are the same, the locating points on the frame are what's different.

Exactly right......match the upper arms to the frame.

64-67 uppers are longer and will not fit 68-72. lowers are the same 64-72...
