Want to convert my drum brakes on my 83' to disc. Will the GSL axles of the same year swap or would I have to change the complete differential

Not sure if the axles will work, you might as well put the whole GSL rear end in since it has limited slip and disks already on it. Its an easy swap, you could do it in a weekend easily.

You need the caliper brackets that are on the disk brake axle housing. Swap the whole thing out.

For it to turn out right your gonna need to swap the whole thing, plus grab the e-brake cable, and the doner car driveshaft. You will also be gaining a limited slip third member(pumkin).It's a straight forward job, about 3 hours. IMO.

I didn't want to start a whole new thread and I figure its sort of related so I'll just ask here. Will the LSD from a GSL-SE fit in a GSL rear end??

What year GSL ? 84-85 yes. not the other years.

What year GSL ? 84-85 yes. not the other years. 84-85 axles are larger diameter@ the splines.

from a 84-85 GSL will hold a 84-85 -SE third member,,,if i'm not mistaken.

One other thing. The rear brake bias is different between the drum and disc brake setups. You need to swap brake master cylinders to do it properly.

Why are you swapping to discs?

yes the master cyl is different. Why is swapping to disks? isn't the answer obvious? drums blow ***. duh

ever seen high performance drum brake kits? if you do, let me know.

Depending on how the car is used, rear drums can be more than adequate given the front does most of the braking.

Where rear disks really have a functional advantage is in repeated high speed braking operations usually only encountered in road racing or lapping days on track. Even there, there are ways to make drums work.

If the use of the car is moderately aggressive street driving and autocross, drums work fine. Spend the time / money elsewhere.
