Found an 87? 325i with ABS vented front and rear disk brakes at salvage yard. I have a 84 318i with unvented front and rear drums. I'm getting the front calipers and rotors. I'm also getting the rear calipers and rotors as well as the trailing arms and parking brake cable. Unfortunately someone got to the ABS system before me. Will I need the front and rear hubs? Both cars are 4x100. Is there anything I am missing? I can get everything for 150.00 but I have to move fast. Any advise would be helpful! THANK YOU.
