floor pans and heater channels
 

i'm just starting to work on the '73 super i picked up this spring, and need to replace the floor pans and heater channels. i was wondering if pans from a standard would work? i have an extra set i was going to use for my '66 but ended up not using them. i know the seat mounts are different, but i'm not planning on using stock seats anyway. also where is the best place to get replacement heater channels? i've heard good things about mid america's parts and they're not too horribly far from me. any way thank for any input in advance.
