I own a 67 and I am running and set of 20x 8.5 bullits all the way around. I am running 66 mustang 620lb coils in the front and reverse eye springs in the rear with 1 inch lowering block. the tires are 255 35 20. they rub just a little in the front but, if I was to run a 30 series tire I would be fine . My tire is 28 inched tall and I am running 1 inch spacers in the front. didn't need them in the back due to the fact that my rear is out of a 63 galaxie. which is 2 inches wider then the fairlane. on the spacers swap to longer studs and run them that way. I do not like the kind that bolt on and have new studs on them. I had a wheel fall off because I didn't have them torqued right. The wheels came from an 05 mustang. every wheel and tire place claims they will not fit a fairlane. I say they are wrong. you can check out a pic of my car on my profile. if you want email me at un-fairlane@hotmail.com and I will send you more pics
