I got a drawtite hitch off the local craigslist. U-haul could not think outside the box to get a hitch that would fit my 59 longbed. Their computer went back to 1963. I measured the width of the frame and crossreferenced it to the new hitches. It appears that a 34 inch wide frame is common to chevys up through the 90s and beyond. The hitch I got fit perfectly underneath the barden bumper, however being a longbed... the hitch bottoms out easily on a slope. I plan to modify the hitch to go through the barden bumper for about 2 1/2 inches more ground clearence.
