Yours is a lofty goal. Good parts still made in America? I thought Wally World had cut prices and quality to a point that American companies could not or would not compete. In a recent quote from a Chinese trade diplomat he stated, "China can produce whatever quality the customer is willing to pay for." If we ask for cheap prices THEY will produce cheap quality. That said, I think PRECISION REPLACEMENT PARTS CORP. makes their own rubber. Even if they don't, I've used Precision rubber seals and I find them to be very good. I know LMC, at one time, was using Precision. You can contact them at 1-800-367-8241 or email at : info@prp.com GOOD LUCK I have the same attitude about a lot of overseas repop stuff.
