Know any place that makes cheaper aftermarket seats?

I've been looking for seats myself, but like you mentioned all of the nice looking, adjustable, comfortable seats are like $400+ dollars. Good luck and keep us posted if you find anything.

By the way, your list of mods is excellent, that's exactly the direction i'm going (a little different because my car is lacking more in some areas -7.5" rear needs to leave- and i'm carbed, but it's coming along).
