Hey Wildmani, thanks for the compliments. My buddy has plain old chevy rallys that he bought at a local swapmeet. Right now he has 15X8 in the back with a 245-60R15 tire which clears with no problems and 15X7 wheels in front with 225 60R15 tires. the front ones rub a little at full lock. He also has 2 other 15X8 wheels that he will be refinishing this winter to try on the front in the spring because the back-spacing is different. I can measure the backspace and such on these next week if you want to try finding a similar setup but like I said, I don't know the original application since they were a swap meeet buy. Just for reference, the seller wanted $350 for the 4 whells at 9AM but Francois picked them up for $180, 15 minutes before closing.
