I did all Poly on my '89 Diplomat police car. It is definetly firm but not harsh and it's driven almost daily. Most came from firmfeel, but I got energy suspension for the sway bar end link bushings.
As far as Moog; I had heard they may have gone to some over seas sources so I emailed them. They responded they do have some countries of origin other than the US, and if I emailed the part number/numbers they would advise. I emailed my part numbers (upper/lower ball joints and tie rods and ends), and they responded they were US made. That was for my Diplomat. Who knows on other stuff, but if you go to the "Contact Us" on their website and email them the part number/numbers you will actually get an answer!
