Interior help
 

just pulled up my rubber mat and the insulation under it was rotten and rusting the floor. Were can I get some replacement heat insulation and what is best to put under there?

same thing and you can get it from jegs, summit, lmc truck. just about anywhere but you also got to fix where the rust is coming from. i am having the same problem. i need to get the floor pans and replace them. the side that are very common to rust , rusted on mine and i replaced my carpet about 4 years ago

I am not sure were the rust is coming from looks like at one time the floor was wet. Only rusted thru one little pin hole. Sanded and primed also kick panel is rusted a bit.

Ebay sell the piece you are looking for.

what i did i pulled up the carpet and all and looked in the cab whiole my kid hosed down theoutside of the truck usually its one of the vents left or right take aopart and fix
obnce ya do the floor repair ya may wanna undercoat the floorboards before ya put down the insulation ( which ya can get at any auto parts store, catalogue or ebay) and then either the mat or carpet
