I've have a miner problem with the floor pan in my 78 f150 . Where the seat bolts to the floor in the rear the floor pan is rusted out and the deck part right behind the seat is pretty gone . Is the floor pan in a 88' cab different in that area ? And the door jam has rust holes were the rain drip roles down the side of the door in the strait area if any one knows how this can be re-paired that would be great because other than those spots the ab is so far good .

 

LMC Trucks would probably have replacement panels. Can't answer about 88 parts fitting. If it's not too bad, just cut out the rust and weld in patches if you have the skills and a welder. A lot of stuff is easy to make, but sometimes it's better to buy a panel and replace the whole thing or just use the portion you need.

 

88 parts wont work. I believe LMC does have new pans, as does Dennis Carpenter to. Depending on how big the area is, it might be cheaper to get sheet metal from the auto body supply store and make up your own patches. But that would depend on your skills and what you want it to look like. As for the rust holes on the door jamb area, first you need to find out where the water came from and fix that, otherwise what ever you do the the rust area will fail again. I would again just cut out the rust hole and weld in some sheet metal in those areas to.
