Looking for anyone with Unibodys who wouldn't mind measuring the width across the top of the tailgate and inside where the bed where the tailgate goes. I have quite a gap in this area and need to know whats the normal spacing. My measurments are 661/2" across the top, and 671/2" in the opening at the top and bottom. Thanks.
just picked up on your question. Just measured my 63 ford unibody shortbed 67 1/2 top and bottom. space on either side about 5/16. my truck is low milage. if pickups are used with the tailgate down the sides will change position overtime. tailgates should always be closed.
