Tore out my carpet tonight and have some rust and cracking of the floor under the rear of both front seats. I was going to cut some 12 or 14 gauge steel and weld/bolt it on then remount the seat. Any ideas on best fix? I could cut the floor out of another K5 or just use steel. I think I should also seal between the so nothing gets traped between them. What do you think? Maybe Herculinner on floor and dump the carpet for good. Thanks 87 Blazer sm465 & 208.
