I've searched a couple online vendors but I didn't have much luck. Both the drivers and passenger sides will need to be replaced. Also are they supposed to be fiberglass or metal? The floorboards on my car are a mixture of many things including foam insulation. Due to this, I can't get my seats in with any more than 2 bolts.

The steel floor pans are available from mid america motorworks around $260 per side. Their catalogue states that they fit '76-'82 models except early '76 models with fiberglass pans and '81-'82 models with power seats.

Heya
I think upto late 75 or early 76 the floorpans where polyester, metal brackets where added to reinforce the areas that need it (seat mounts, seat belt fixations etc).
I dunno if anyone ever completely cut it out and replaced it by the steel ones like this http://www.ecklers.com/product.asp?pf_id=42686&dept_id=1427
Finding the metal parts is more of a pain, and the ones I needed I could only find in junk yard vettes.
I would not fix the belts or the seat to just the fiberglass, not even with two bolts holding the seat down! In case of an accident it will all rip out and that's probably not really what you want

Even on older models with fiberglass floor I don't see why you couldn't make the steel floor pans fit. All major vendors sell them and you should be able to weld them to the trans tunnel and rocker channel.... only two bolts for one seat is not very safe.... one day your butt goes right thru this crap and hits the road ... :down:

do it once ... do it right....

OR:

we never have the time or money to do it right but we always find the time and money to do it all over again.....often after we got hurt....

Oh i'm not driving the car due to this problem, i had everything fixed and when I had the car on a lift I noticed insulation between what looks to be a stock floor pan and something covering it. I have visions of the seat and I falling through the floor and getting a couple boo boo's. Thanks for the advice guys, I unfortunately do not know how to weld, but my uncle does.

Welding that thin sheetmetal is tricky, I am also cheap so I glassed in my floor pans after a thurough cleaning and painted with POR15. Structurally they were ok where the seat mounts, but the lower floor under the passengers feet was cheesed pretty good
