How about sealing the inside of the cab prior to the Matt install(floors and fire wall) with Bed liner material of like, to seal out fumes if any that permeate from older cars.
I got the idea from Coupe King's site to reinforce and seam seal certain points in the cab then etch and Por 15. It's overkill but helps prevent against flex and rust, especially in the cavities. I would treat all the metal first before applying any type of bed liner. The inside of the doors and any place else water may get into that cannot be released quickly is a candidate for that application.
