@Hemiorangeswinger nice build lots of work I've been following this thread
Q? did you use the black plastic gasket that goes between extension and fender ?
Thanks! I don’t think there’s a gasket on the 70+ darts? I know the B bodies had them in 67+ The factory just gobbed that dum dum (I’m not sure of the exact name, but it never dries) on the studs.
