I would have done the door pins before the car went to paint!!!!! I was thinking this should be in the Body shop forum?
You can also down load the March Issue on here, which does door hinges and pins.

If you don't want to rebuild them yourself Wille does excellent work and send them to him. He did all my hood hinges for me.
