Recently I picked up a 1980 528i along with a 1973 3.0si.I am planning on using these cars primarily for parts for my conversion from auto to 5 speed manual and from carbs to FI.The 3.0si has limited slip so thats a bonus.My basic question is what other parts from the E12 528i can be used on the coupe?Is the wiring harness a possibility? Any info at all is most appreciated.TIA. Brian
