Most vendors I have seen sell stuff made by Auto Custom Carpets. It seems a little light, but the quality is good otherwise. I've worked with three different vendors on four different cars. Each time the carpet has come in an ACC logo 'ed box.
I've had difficulty getting correct heel pads for '66 Darts. In both cars I restored, the heel pad had "dots". After the first vendor sent me a carpet with a ribbed heel pad, I learned to specify the dotted one. The second time, the vendor (different vendor) contacted me to ask if I was sure. Since it doesn't cost any more to get the carpet with the "correct" heel pad, you may as well get what you really want now so you don't have to make excuses later.
