What a difference an inch makes.
Well I picked up some 1x1 steel tubing, and I've spent several hours in the garage over the last few days. Cutting, welding, grinding, repeat. Anyway the drivers seat is done, but still working on the passenger seat. Since my wife is so short I'm raising hers 1-1/2".
Looks a lot more secure with the steel tubing, just haven't bolted the seats back in yet. Gotta figure out a safe time to go to the hardware store for some grade 5 or better bolts. I'll try to get a couple pics up soon.
