Done tons and tons of wheels on 67-68's. Some 67-68's can squeeze a 10" if you roll the fenders and you get lucky. I have a 68 now, measured and measured, it will not take a 10. The 18x9.5 with a 275 is going to take a bunch of work to get to fit without rubbing and the backspace is spot on. Wish I could have got the 9" to help pull the tire in a little more and it would fit the car. I have a 69 as well, should easily take a 10" according to all the forum jockeys right? Nope. Rubbed all over the place at the ride height I wanted. Built a set if 19x9 for the rears. Fit like a glove with the exact same amount of "wheel lip" as the 19x10 and more than I could get out of the Rushforth 18x10's. Basically at the end of the day, you are going to be running a 275/40/18 tire. Does it really matter if its in on a 18x9 or 18x10?
