Somebody please help!!

I got a 69 C10 and the bed is all rotted out. A guy not too far from my house has two stepside beds in his yard for 73-86. Would the earlier models fenders bolt up to the newer bed sides? are the mounting holes the same? pretty much what i want to do if you cant tell already is get that bed and put the period correct fenders on it but i wasnt sure if this was possible? somebody please help me asap because the guy with the beds supposedly has somebody picking them up on sunday so if this can work then i need to act fast. thanks in advance.
