TX 85-84 gsl rear swap

I have an 85 GS, with drum brake rear end, it makes a lot of noise and isn't the bearings..... so, I bought an 84 GSL for parts, and it has disc rear... what all do I need to take off of the 84 to change over to the 85?

The entire rear end should swap straight in. I believe that the ebrake cables will have to be changed as well. The hard lines for the brakes are a bit different but you should have no problems getting everything straightened out with what you have.

Since you are swapping out drum for disc, you should swap the proportion valve from the GSL also.

According to the parts manual, the prop valve is the same for all '84-85 models, so no need to change that. The earlier models had a different MC and prop valve.

So, you just need the rear end, parking brake cables, and the soft brake line between the MC and the axle. That's what I did and braking is spot on.
