I have plenty of room on the backside...maybe 3/4"-1". I also trimmed the lips down to 5/8" wide for extra tire clearance. I may could have went 1/4" to 1/2" wider on the rear end, but everything seems to look dead on after mocking it up. I hope to have it on the ground next weekend (for the first time in 2-1/2 years), so I'll study it better then.

Remember, you can always add a small spacer, but it's a pain to cut the rear end again. Measure 50 times, then call Frank!

Thanks Chris.
