1965 Valiant 100 parts interchange questions.
Welcome Deegan,
The windshield should fit.
Are both cars post cars? If so, then the doors may fit. You'd have to double check the body lines as I don't have pics handy at the moment. Just re-read your post. Do you want JUST the door panel inside?
I'm picking up a '65 Signet parts car, if there is anything you need just let me know. There is a member who has dibs on a couple parts but I'm sure there will be more available.
