I recently ordered two carpet sets from them for my 1969 Chrysler Town & Country station wagon and 1973 Dodge Coronet Crestwood wagon.
For the T&C wagon the carpet fit very well but it is still some work to get them installed. Razor blades for trimming the carpet don't last long and the backing is pretty rugged, making the install tedious. This carpet was the standard loop pile and it turned out looking really nice - just took a lot of careful cuts to get it right. This model has the floor mounted seat belt retractors with rectangular covers on them but the carpet molding did not account for that correctly, so except for that detail, it was pretty straightforward to do. That extra hump due to the seatbelt was a bit of a pain though to get it looking good but I was careful and thought through the implications of each cut to the overall shape I needed to get.
For the Crestwood wagon, I ordered the ultra plush cut pile with mass backing to try it out. It is was far more classy than the cheap kind of crappy cut pile originally in the car from the factory and the trimming was just a little more tedious given the mass backing directly attached to the bottom of the carpet and the jute was glued under that. So everything was significantly more thick than the original and much more substantial. On the Crestwood models (and most 71 - up models) the seat belt retractors are separate assemblies that are added on after the carpet installation. Overall, this install was significantly easier than the T&C install due to that one improvement in Chrysler's design of the seat belt retractor (it doesn't look nearly as clean as the assembly that is mounted in the floor on the T&C but given how much easier the separate install is, I am happy to put up with the not so neat appearance of the seat belt pod on top of the carpet mounted to the interior side rails rather than in the floor. But given the extra thickness of this plush carpet, I had to find some longer seat belt bolts, the C12 marking on the head of those bolts. If you don't have any laying around, you can get reproductions of them from Vans for $8 each.
One other comment, while the heel pad was correct on my T&C, it was not identical to the original one on the Crestwood - but given the improved look of the carpet, I let it pass since this will be more of a driver type vehicle than a fully restored one. So you might want to see a photo of the heel pad before you order to make sure it is correct if it would bother you. Normally it would bother me, and on the T&C, that was more a full restoration but its heel pad was correct out of the box.
But overall, I am very pleased with the quality and appearance of the interior of the wagons now.
p.s. I would personally recommend separately putting any mass backing directly on the floor pan first and then just ordering their carpeting without that option only because it was more difficult to get the carpet to sit flat in a couple spots with the mass backing (and easier to cut too, but not that much harder in terms of the cutting).
