    Well, wouldnt ya know...more questions.
    Last weekend i finally finished painting the bed, and was putting in the insulation when i noticed that the rear sealtbelt on the drivers side(the part thats bolted to the floor) was about to break, so i thought i would bend it back and maybe it would hold.....NOT! Broke right off...now, the bolt is rusted on pretty good, and wont come off...anyone know where to get another on of these peices,with the bolt so i can grind it off.. LMC doesnt have one...that I know of....?? Also, the bolt that holds the rear bench seat to the floor is all F.U.B.A.R.'d and the threads are srtipped!...anyone know what size tap to use and the measurements?? Or any other solutions??....And, I lost the Torx bolt for the front passanger belt...I need size/alternative I know its a 50 torx bit but thread size??....thanks again!! I know this is alot!!!

    I'm pretty sure the bolts that hold the rear seat to the floor are 1/2" NC. Try running a tap through them and then some new bolts (grade 8)

    Did you try some heat on the seat belt anchor bolts?

    NC stands for National Coarse. For 1/2" it should be 13 TPI (threads per inch).
    NF is fine thread, there are a few others too, pipe thread, tapered pipe thread,etc.

    The Torx bolt for the front passenger belt is the same as the Torx bolt for the front driver's belt. Also, aren't there two identical bolts that hold the rear seat to the floor? It sounds like you already have one to use as an example.

    can i just cancel those pathetic oval plates, install a steel plate and use regular bolts instead of those annoying torx bolts?
