FENDERWELL HEADERS
I noticed this a few weeks ago and had front wheel clearance issues on my 73 w 2" primary fender well units myself. Yes you can keep the 15" front wheels just go w/a lower profile. We seem to like our skinny fronts & a majority end up w the "skinny" 165's on them usually 80's an actual 165 80 r 15 is over 26" tall. They will rub slighty on deep turns esp. the right turns. So I went to another car (that I had) and found a pair of 165 /65/r 15's. I measured them .... Same damn height... Go figure. I went to the tire store and we ran a tape on a couple of brands. Geeze these tire mfg's are like Jean mfg's these days. Some aren't that accurate. I ended up with 185 55 r 15's to make sure. I may have over did it a bit. I plan on pulling the front wheels off the ground, so I went small. These are only 70$ a pc and still rated at @ 130 mph
