I don't remember to much trouble getting the '37 hood to line up. Maybe I just got lucky the first time :confused: . I would go back and check the cab. It has to be square to the frame or nothing will line up. The front radiator support only has a slight side to side adjustment room but plenty of front the rear. The V-rod is used to align the top of the radiator support to the bottom so the gaps line up on the hood sides top to bottom. If the cab is off center the hood will be pointed to far to one side and there just won't be enough wiggle room to correct it. Also the hood ornament should be inline with the hood hinge. If its not in a straight line the hinge could bind and you will all ways see the error when driving :mad: .
If I remember right there are eight cab hold down bolts. The four in the front (2 per side) are solid to the frame with a little rubber insulator. The next set by the front of the seat riser is bolted with the springs under the truck in the frame rails. The last set behind the seat and fuel tank have the springs inside the cab. The four rear bolts allow the cab to flex with the frame thus the heavy duty springs under the locking bolts. There are also four wood blocks on the rear cab mounts, the front two are shorter then the rear two.
Something else, my hood won't lay flat or line up very well till I lock the shut. Joe
