I'm 6'2 and found the original seat (aside from being light on covering and padding) to be just perfect.
$150 seems like a reasonable price for getting a kit for re-doing the original seat.. where can you get it?
American Classic Truck Parts dosent seem to carry anything for a '46.. in fact, most online vendors seem to start at '47 are the seats the same?
I had called around for estimates at local upolstry shops, and seemed like all the folks I called wanted $300+ to redo them.. thats a little rich for my blood for a seat.
