Floor/Bed Mat dimensions

[NateObee]

I've got a mostly 72 Blazer, some various parts are off a 69 sub. I love that the top comes off alway to the windshield. so of courae i've got the top off all summer, as it should be. Summer only though, I do live in colorado. when i got my baby, it had Carpet in the bed and cab. but after many rains, and am oil leak at the pressure guage, i decided that i needed to ditch the carpet for something waterproof.

I'm doing some interior body work, replacing the fabric side walls with sheet, i've built some speaker boxes in under that roll cage in front of the rear wheels, and have seamed them in with some sheet metal. i'm going to paint the interior with a "Road Warrior" bed liner. but i wan to reduce the noise by droping in a rubber bed mat. and a full cab rubber floor mat. i can't find anything on line speficialy for the 72 Blazer.

my question is, can i use a bed liner/floor mat for a short bed pickup?

Do the have the same basic dimensions? and bumps in the cab? I realise i'll have to trim here and there for my mods. I think i can, but does anyone know the measurements? are the wheel wells at the same distance from the tailgate?

Thanks.
