ive heard that the 65 val front wheel opening is close to the wagon rear opening

ive seen this done sort of the other way around. my dad cut the openings off of a wagon and molded them in to be the rear openings on a 64 barracuda. before doing this as the finished product he did do it starting with front fenders and it wasnt as clean. sure is a lot easier to find a front fender than a decent car to cut the rear quarters off of. good luck
