Karfer, is that a spotlight on the other side? They used that bed up until 63', from 61'-63' they were Unibodys, stepsides, and those "boxer" beds. I have a 62' short uni and a 65' short stylside, 64' they changed to a bed that folowed the lines better, 65' was the 1st yr. for the Twin I beam susp. Good lookin truck, they're alot of fun to drive. You need to join the slick 60's, 61-66' ford truck club.
Good luck
Charlie
