Yeah that's what i would do as well, although i would look out for some cleaner ones than i got,
on a good note, the door i got is from an early 75 as the pic shows bullet mirrors, but there are no signs of rust on it, haven't looked on the underside but seems pretty good all over, was looking over on the 75 site the other day about the rustmaster protection, £385 for a single car to have everything rust proofed, may well consider it in the future, there is a discount on 10 cars going at the same time
