after dragging home a complete 9-bolt posi/disc with 2.77s for $125. yesterday, thinking a simple gear swap up to 3.42 was a good deal......then finding out that gear swap will cost more than I can build my complete 10-bolt for......Im thinking.
Has anyone taken the disc brake system from the 9-bolt and put it on a 10 bolt? Did some measuring for the bracket/backing plate bolts and they seem to be off 1/4". I'm thinking this should be no big hurdle and looking for opinions or experiences of others.

Thanks,
Shannon

 

The disc brake setup on the pre '89 rears is not too desireable.

I would suggest you try to sell the rear you have, and start over.

Ed?

Here....and I don't need another 9 bolt, unless someone has a 3.45 with a good posi available....cheap.

I saw in another post that you said it's an '86 9 bolt...correct?

If so, those (disc) brakes suck. Your best bet is to find a set of 9 bolt backing plates (Andy is getting them made.) and install a set of '89-up PBR brakes on your 9 bolt as seen below.

 

Here's my rearend...(insert jokes here)...

 

when i swapped the 10 bolt from my 84 with factory 4 wheel disk it was a direct swap to the 9 bolt. I don't recall any problems at all, but it was 10 years ago
