As is typical, my driver's side seat foam has broken down, and the cover needs to be replaced. I've found replacement foam, but am having a difficult time finding vinyl OEM replacement seat bottoms. I prefer both left and right (to keep them looking the same. My truck has work truck interior, very basic, manual windows, rubber floor mats, and so the seat covers are slightly different than those with SLT trim. If I have to use SLT bottoms, I will as long as they're the same charcoal grey. Anyone have a good source???
