Be really careful when buying a donor car that has been hit in the front. If the point on the chassis where the eyeball bushing mounts have been moved and/or pulled back into shape if you ever hit it again, it will be soft there.
I bought a 1986 325e 4 door 5 speed car to drive on the street, the car ran and drove, had a lightly wrinkled drivers fender and valence and the LF wheel was majorly bent but the tire still held air.Both control arms were worn out so the first thing I was going to do is replace them and the struts. The passenger side went fine but the drives side strut would not come off the ball joint. I noticed that the bushing was torn out of the eyeball but the control arm did not look bent. I had to jack the strut up to get it off the ball joint, it was about then I noticed the wrinkle in the frame rail…Seems the PO hit something hard enough to bend the rail but not really affect the alignment of the car. I have a bunch of old race bushings laying around so I figured I would make a prototype of something that would line up, put the car back together and see how bad it is…grinding out a bushing so much that it slide 1/4 inch further forward was still not enough to get the bolts to line up. I then took the inside of an old powerflex bushing stuffed it in an eyeball with the metal bush torn out and JB welded in place after test fitting a few times. If there are not any major alignment issues and the car is otherwise OK I will mount a factory bushing in an eyeball offset to the back and pinned in for a permanent fix. Be really careful of a car that has a torn out eyeball bushing as having to get a car streached back into shape is $$ and it may not perform as designed in the next mishap.
