    I need some help guys. I have done a search here and found little in the way of previous posts. As most of us do, my floor has cancer. I need the piece from the step for the rear seat to the rear of the front floor pan (front of the seats). I can find absolutely nothing on the web for even rear replacement panels. I find it hard to believe that with the trucks having such a rust problem that nobody makes the parts. Does anyone have any info on where to look? I can't weld in patches cause whats there is so thin it burns right through. Somebody mentioned on a previous post about a one piece part from GM, any body have more info?
    Thanks in advance.

    Lol, you are in for some real fun. I've been pi$$ing around on my floors since May. Right now I have quarter panels hanging in mid air with no bed in between. The brand new galvanized GM bed goes in next week. As for the floors you are pretty much screwed. You can get a whole new floor for probably $400+ from GM. It takes alot of work busting all the welds out to get the floor pan up. There some panels for up by your feet you can buy but thats it for patches. What you have to is pull your carpet out, drill out the spot welds on the bad area and begin to cut out the majority of rot. Below your floor is a subframe that may be still good and all you have to do is set sheet metal over that and weld it into place. If your floors are like mine than your subframe and cab mounts are in sorry shape. I had to cut out whats left of those put in some 1/8" square tubing :-D , lets see that rot out in my life time. You shouldn't have a problem burning up the metal if you use a 110v MIG welder, they're meant for body work. I use my miller on the voltage setting 2 or 3 (out of 4 positions) to weld sheet metal. The trick is to have your sheet metal overlap the good metal around a 1/2" or more. Than weld it all in and put on some sealer. I believe the original GM floor pans are severly flawed and about anything a half way bright person can rig up in there garage is better. Good luck cause you're going to need it.

    I gotta get my arse in gear with the pics. Im pretty much living at my uncle's so I never have a computer and no CK5. I got it in mid tear down right now, just quarter panels in mid-air, lol. Homemade floor pan up front too, with square tubing for the subframe. Its alot of work because mine suffered from some quicky repair work.

    I spend a month out there thinking Im the only person on earth who's attempted and bed swap and I'm just soooo special. I come back and everyone's throwing a new one in, lol. Pulling the old one wasnt quite as easy as I thought, but not too bad. The spot welds on the wheel housing sucked for one. The rest just ripped off because of rust. I got rust free tailgate posts off of an old '86 3/4 ton laying by the shop (had been in a bad front end wreck). I went crazy with the torch and just cut off the back and drug it to get my stuff.

    Don't know when I'll be back in town but good luck Riz.
