I have the UPR loop...I think I bought it for $30 at WFC last year...took me about 2 hours to install because I had trouble getting the seats back in...Very easy to install though...just need to put the car on ramps, take the seats out, drill 4 holes in the floorboard for the bolts, and then just tighten everything up...there's even an indention in the floorpan that tells you where the loop needs to go...
