The problem I have with the IFS yota box is that the forward most bolt barely has any clearance from the radiator hose, I cut a nut in half and cut the bolt down just so I'd have maximum clearance.
High steer stuff... definately caused more problems than anything, since my axle is cut down 6", I barely had any real estate to fit stuff. Honestly, I wish I went full width on the front. I also got my expy d/s extended three inches to accomodate moving the rear axle back about an inch and the SOA, i'm going to be ordering a new d/s because instead of replacing the whole piece of tube, they just welded in a three inch section of tube.
