[steakandracingfuel]

are these two cars the same wheelbse? i have an uncle wanting to fix up his cougar cuz of sentimental value and he has a chance to get a mustang backhalf and frame and was wondering if these 2 cars can fit each othwers wheelbase

I could be wrong but i think the 65 mustang is alil smaller not by much then the cougar. If there were both 67 then i would say try it but i think the 65 mustang is narrower then the 67 cougar.
