Which seat cover manufacturer do they use??

Last I read, they carry PUI. At least thats what I got from them if I remember right. That was years ago when I purchased my interior stuff from them.

I called them a few weeks ago, as I am in the market for some seat covers, and the rep on the phone told me that they carry Distinctive Industries. Their catalogs say Made in the USA, so that would rule out PUI I would imagine
