I have a 58 1/2 ton. The original hinges were shot, so it has repro hinges as well as a repro latch assembly with the original striker plate attached to the hood. There is considerable "up" tension on the hood when it is latched. It "works" on the latch, and after five minutes of driving it has worked itself up off the proper height by 1/2-3/4" or so. Question--when the hood is closed and latched, should there be "up" tension on it? What bolts were used to attach the latch mechanism? Thanks
