The Mar-K paperwork that I'm using says to use indented head bolts where the rear sill attaches to the bed side. I cant really see any reason that they need to be indented head style. Is this just an originality thing, or is there some good reason why they need to be indented heads ??? My truck is 1953 half ton.
