I was replacing the rumble lid bumpers on my roadster. Was looking at the pivot/rotation point on the hinge. It appears the upside down A shaped hinge bracket that attaches to the deck lid should be pinned to the shaft with shaft rotating in the cast piece bolted the the inner fender/trunk wall? Is that correct? Mine pivots at the bracket attached to the lid. There is a hole in both bracket and the shaft that makes me thinks there should be a pin of some kind in there. If the is correct what does the pin look like? Thanks
