this was last couple weeks but on my 88, we ripped out the seats which were completely falling appart from rust and being held in by zipties. the floor is also pretty baddy rusted out so we cleaned up the rust some, sprayed some rust converter paint on it, and used some cut up pieced of rubber liner to cover the holes. its not going to add support but i figuered something is better than nothing at covering the holes and preventing water from coming up through them
jsut like i did in the 96 but without the sound insulation, we bedlined the floor with a thick layer and let it dry for about a week. you can see some of the areas where we covered the holes. the bedliner should help protect from water getting under the flooring and causing further rust
once dry we put down a vinyl flooring. its a Auto Custom Carpets kit from Automotive Interiors.
went to the junkyard and looked for any kind of non-cloth seats i could find. since its a mudtruck, i want to have seats i can wipe the water away once wet instead of sitting in wet seats all day for a multi-day event. out of a few hundred vehicles these were the best seats i could find from a ~2000 Chevy truck. also did find a cente rconsole form a 95 bronco.
problem is the seats are meant for a flat floor unlike the bronco that the floor is raised for the seats so i had to weld up some tall brackets on the outside rail to make them work. also made pads for the inner rail for above and below the floor to reinforce the metal. the brackets also have plating under the floor to reinforce since the rust is bad in that area.
i tried to swap a F-series tailgate onto it since i dont need rear window and the old tailgate is falling apart at the seams and heavy. when i mocked it up i decided against it, the striker, hinges, and cable supports were in very akward locations that would requires too much work to bother. also the f-series tailgate being soo much thinner looked really wierd. instead i gutted the bronco tailgate to make it very light and put some diamond plate to fill the window opening. should keep rain out and hold the tailgate together solidly. could be better but im fine with it
