hey guys, ive read the whole www.thirdgen.org/ls1reardisc swap info. but i have a disc rear( the old delco ones ).. does this make it easier?
also about the fronts to upgrade the fronts to the ls1 fronts i need to fab the spindles.. ed can i get some input on this? ( or anyone else that knows?)

thanks for your time
Douglas

 

Yes. I'm unsure about LS1 calipers, but 89-97 calipers are bolt-ups with the correct backing plates:

As you see, I chose 1LE fronts as well. These required a simple spindle modification.

Glad you made it Cam boy. You might want to PM ebmiller to getfaster input. or refer to the stickies at the top of this forum. James is right about the backing plates. Changing those would allow you to run the 89-97 PBR's. However, you may experience what I did when I swapped a 3.27 88 rear into my 89 car. I had to recenter the caliper carrier in relation to the rotor. This meant adding shims on between the carrier and axle housing in order to provide the proper clearance. Something about 9 bolts with the old and new setup. I think the flange on the 82-88's was thinner that that of the 89+ 9 bolts. Anyway, other than that,you may need new ebrake cables as I mentioned before, due to the different in design. The delco's used a weighted system and a different hookup. They also alternated with one cal trailing, the other leading. Both PBR's are setup to trail. Just something to think about.

BTW, do you have a ten bolt or a nine bolt rearend? That will also determine a few things!
