I installed the swivel from Discountvantruck.com today. The swivel arrived without any instructions or documentation whatsoever, just a swivel in a box with some nuts and bolts. But is is very heavy duty and worked fine for half the price of swivelsRus. I found it easier to remove the entire seat and base assembly first and then separate the base from the seat, I had a few issues if anybody is considering this swivel. (1) There is no accommodation for the bar that engages the manual seat slider so my first pass at install the bar is up against the swivel so the slider won't work. My solution is to remove the seat base and spread the sides to remove the bar that activates the slider. Then reinstall that bar UPSIDE DOWN. That lowers the pivot creating a little room to move. Also, add a couple washers to each of the 8 threaded posts to raise the swivel up ~1/8th inch. Finally, you may need to bend the bar just a little so that it arches a little more toward the floor in it's upside down position. (2) the wiring hole in the center bolt of the swivel is too narrow for the wiring harness to pass through. So after unplugging the 2 harnesses, I snipped off the plugs on the wire coming from the floor (not on the seats) and I spliced in a generous extension for each wire on the 2 plugs. then I plugged them back into the seat wiring harness, fed the wires through the hole, and connected each wire to it's original source wire. The airbag light turns off after the car starts, so seems to be working. Last item is the plastic trim on the right side of the seat. It will not go back on properly with the swivel so I had to trim just shy of a half inch off the bottom. Total install time more like 3 hours, not the half hour listed on the website, but it's in and works great.
