If you watch long enough,sometimes they do have fitment problems,and have to switch wheels,or profiles on tires. Did you see the build up on his personal p/u? First they positioned the new front end at ride height, positioned the frame,and filled in the difference. They still had a heck of a time deciding on wheels,but it was just a matter of cosmetics rather tham fitment. What I do myself is block up the car,remve the front springs,support the lower a frame with a jack set at different hts.and try out different combos[borrowed of course] to see what fits at varios hts. Hope thid helps you, Hank
