My sister ordered a set of the brown ones for a horse drawn thing I am building for her, so I'll get to check them out and see if I like them. I see several styles of black ones that I like but black isn't happening and other color choices are few. I like that the brown ones are deep. I have never really driven a car that had the seats so close to the floor where your legs go out instead of down, which looks like it will leave a lot of weight on your tailbone and not so much under your thighs. Now you younger guys might be ok to drive with your legs folded up and your weigh on your tail end but I am too old and stove up to roll that way. So I think for me, the deeper the seat is, the better I will like it. If that 1742 was 22 inches deep, and red, it would be perfect.
Another thing I have been thinking, just for fun and temporary is to put a couple of the old steel machinery seats in. I have some, off a dumprake or horsedrawn mower. I'd have to put some sort of backrest in.
