Has anyone had any experience with aftermarket seats for a 328?
They would be the same as aftermarket seats for a 308 since they're interchangeable as far as the railing mounts go. Do a search using the words "sparco 308" and you'll get lots of hits. In fact, here's a link specifically discussing them in a 328: http://www.ferrarichat.com/forum/showthread.php?t=7086
