I am currently trying to squeeze a 3.5 litre six from a 1978 635 CSI between the fenders of a 1982 e21 320, and I am in deperate need of engine mounts. Those of the e21 B6 alpina 2.8 and 3.5 should work. Drawings of these mounts would be very helpful, as well as any other information concerning this 'minor' engine swap! Please help me out!!!!
