As i expected all i found on the rear diff was rust and some more rust. Is there not some sort of method involving jacking the rear end and spinning the wheels?
Also the wheels read Alpina on them in the centre, they actually seem to be in very good shape.
The guy i bought the car off of also has some more wheels so i might just go see if i can find the matching 2.
What are these wheels are they rare are they sought after?
Thanks for all the info!
