seal/weather strip question
 

Im doing some upgrades on my 1970 C20 brush truck and would like to replace the hood to cowl seal along with a few misc seals. Anyone have a NOS they would like to sell, or is there an American made aftermarket seal being produced? Would also like to replace the rubber floor mat but it has to be quality. Can anyone who has replaced some of the rubber on their vehicle point me in the right direction for quality parts? I would like to buy American.
