Looking for hinges for the fishbox on my '91 20' Grady White overnighter. 2 boxes, 4 hinges, 1 of the 4 is missing. They're aluminum "T" type hinges, 2 3/4"W X 1"L, 2 countersunk, machine screws w/fiber self-locking nuts per leaf. I'd like to go with stainless steal, although the style/shape is critical as the lid and deck are molded to accept that specific hinge. Grady White doesn't have record of hardware for specific boats (maybe age has something to do with it). I appreciate any ideas as my search continues...
