I purchased a 66 mustang coupe. It's a 289 2bbl. C4 trans. Only a 8" rear. I would love to upgrade to a 4bbl and maybe more mods. Need carpet and advise for seats. The driver seat has 2 tears in the seams. I would like to maybe install a set of later mustang wheels as long as they fit. Not sure if off sets are different. My car is almost totally rust free and looks good underneath. 14" tires and 14" rims. Any help would be appreciated .
