Swap bench seat for bucket seats (How hard)

[truck69]

I am thinking about taking my bench seat out of my C20 and putting in either bucket seats out of a late model Chevy or seat that is like a drive seat with the arm rest and then the passenger seat will be by itself so they can pull up how far they want. How difficult would it be to do that? What different brackets would I need? Any info or pictures would be helpful.

Thanks. Truck69
