Title says it all... The truck I took the lift off of had 4" blocks with the shorter end of the block toward the front of the truck. Dad says they're backwards and he'd bet me $100 bucks. I've not tightened anything down so it wont be hard to jack it up and try the other way to answer the bet, but thought y'all might save me some extra work since I'm against the clock to get this thing going by this weekend. I hope he's right cause it looks as if the rear driveshaft is in a serious bind. I swear this lift has gotta be 6" because 36" TSL's fit easy, but we trimmed the fenders just to get rid of some rust, lol.
