On my 63 the top left door hinge works fine and the door fits well. I have the hinge spring ( if that's what it's called), but the small roller that goes on it is gone. Would be nice to keep the door open to get in and out. Can this be repaired without taking the hinge off? Or is it necessary to have it off to get that assembly back in the hinge. Can this be done by getting some type of hinge kit? You can sure tell I'm not a bodyman Thanks for your help.
