RE: rear end swap
all you will need to change is the prop valve. booster is fine. as far as the wheels go... i would THINK the 15" wheels would fit, but im not sure so i wont say a deffinate answer on that one. Good luck.

RE: rear end swap
If it is a 89 9-bolt with the 11.655 dia rotors ( check picture)it may be tight with your 15" wheels. I would try fitting them first for any clearance issues before tearing anything apart on the car. I have 17" wheels on my car so clearance were not issue when I made the swap.
Only additional items needed are the Proportioning valve & parking brake cables from the 9-bolt. The brake line fittings are also may bedifferent SAE vs Metric. Otherwise it is a direct swap, just to the normal maintence items before the installation.

RE: rear end swap
its an 87 rear,i believe it should have the 10.5 in rotors instead of the 11.5 in the later modles.i wasnt planing on buying bigger wheels for this swap the ones on there now are in very good shape with a new set of bfg,s.i would like to keep the outside appearence as stock as possible.but if i have to get a set of 16s guess i have to.hopefully there wont be a clearence problem.when the rear shows up i,ll pull a wheel off an check first before dismantling an discovering later when i,m ready bolt up the stock wheels an going.....oh!!!! @#@%$! the wheels dont fit!
