One problem with those seats, and I admit they do look nice, is that at a good price, and sold at such an omni present outlet as Pep Boys, every Tom, Dick and Harry are going to have those seats in their rice mobiles, which would make it look like a ricey Z car in the long run. At least with MOMO, Spearco, Corbeau etc, the price puts it out of reach for the low buck ricer boys.
That said, I may buy a set for my second 240 when I get around to dropping in the ZXT motor from my 83.
