There is a good core set of rears on E-bay for $100 if you want them. Control arms and all, granted steal... But you get all you need to get it done fast
Come over and check the rear setup out sometime and see what you think. Right now my calipers and stuff are rebuilt but sitting in boxes ready for install to the bus when it is time.
Granted it you just need it done fast do not worry about it... Except the 944s will be wider by some degree which could throw off wider fender selection...
Figure worst case $300 (all the rebuild and new rotor pad costs) and you have good discs in the rear with a parking brake.
