all I remember from my brother in law doing the swap from a 87 Disc to a 91 Drum (the 91 was getting the disc rear from the 87) was that the E brake cable needed to be shorted.

is the one you got offered from a 3rd gen? are you gonna put your current disks on the new rear? either way it wont be a problem as long as you hook everything up properly except for the e brake cable..you can figure out how to shorten it or just go get a cable off of a car originally equipped with discs

What rears are you talking about?? 9-bolt or 10-bolt?? Big difference.

Chuck!

What about hard brake line?

If it's the same rear (i.e. 9-bolt or 10-bolt) then you can just take the disc brake setup off your old rear and put it on the new one. If it's NOT the same rear you'll have to use the brakes that are on the new one, which means you need different e-brake cables and a different proportioning valve. The brake lines will be fine if you disconnect them at the fitting mounted to the body directly above the differential.

If you have to use the new brakes then I want to buy the disc hardware from your old 9-bolt rear. (In case I haven't mentioned that yet...)

yeah the rear end came out of a 3rd gen and im going from a 9 bolt to a 10 bolt!!!!

you know that 9 bolts are stronger than 10's right?

You are going to have problems with that swap. The backing plates may be different.

9-bolt brakes will not fit a 10-bolt. However, all you have to do to make the 10-bolt drums work is change the brake proportioning valve to one from a drum rear car. Make sure to get a valve that matches the year of your car, not the year of the rearend, and it will bolt right in. Also make sure the e-brake cables come with the rear.

no matter what u do when changed drums to disk,u have to change the proportioning valve. disk brakes require less fluid to push the pads than drums do to push the shoes.
