73-87 rear end in 69 truck/burb? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know this has been covered before but i came up dry in the search. I know the later rears are wider (1.5 inches, i believe). I could take care of this with new wheels w/ different backspacing. are there any other drawbacks to the later rear ends? panhard bar mounting? I want to do a five lug conversion up front and have the rear match, I have a much better chance of getting 73-87 parts than I do finding a 71 or 72 rear end. thanks, steve

The only drawbacks (depends how you look at it) would be cutting off the spring pads and adding the bracketry for the coil suspension. It's really not difficult, just a little time consuming to get it right.

Is there any width difference between a 69-70 12 bolt compared to a 71-72? Buy aftermarket axles and 5 lug drums to put into the earlier housing.

I also have a '69 Burb. I have a 12-bolt rear from a late 70s Chevy truck to put in it if I don't come across a 71-72 first. Anyways, what I was going to do is: ECE has the coil spring perches for about $50 a pair. As for the panhard bar: ECE also has an adjustable panhard bar that connects onto the stock location on the frame and bolts onto the passenger side lower shock mount. This costs about $120-$130. Then if you lower it, you can adjust if necessary. I haven't looked closely at it for the brakes or emergency brakes, but I am sure if you called ECE up, they would be able to help you out.
