Uh... wow... when you say beat-up seats, you really mean beat-up, don't you? I can't even imagine how they got that destroyed, short of someone taking a knife to them... why anyone would do that is beyond me...
Good luck on the refurbishing though... I'm considering doing some of that myself... I might try to make some vinyl/heavy canvas covers for the front seats so that when I'm at work or in the mud I don't have to worry about getting the seats dirty... that way I can just rip off the covers later and either throw 'em in the wash or just store them behind the rear seats... I would love to change the trim panels inside for sheet metal ones or something of the sort, but at the moment that's just me fantasizing... I might do it eventually though, just to give it a cleaner/utilitarian look and have it stand up better to the abuse I throw at it... I'm slowly working on mounting my sub and amp behind the passenger's side rear panel where the little cubby is on my XL...
