Also, I forgot one, on the GTI you got the parts from it had vents in the door cards. I think to help it close and not be airtight, maybe to just vent. Either way they would let tons of cold air in all at floor level. I took them out and duct taped them from the inside and reinstalled them.
where do you live
How do you adjust the doors? I noticed there was a washer in between the mount on the body and the hinge. to get the door to come up and latch well. Is there another way? Like adjusting the strike pin?
