Thanks for the response, but it's the bolts themselves that come up from under the truck I want to take out and replace with longer bolts so I can raise the seat. I don't know if they are welded in or are rivets, but they seem to be relatively permanently fixed.
I drive a 2002 Chevy S10, dropped 2 1/2 inches with American Racing mags and, of all things, whitewalls. I am trying to get the seat bolts out so I can use longer bolts to raise the seat an inch. Short body, and I want to look over the hood. Has anyone removed the bolts? How?
