65 Chevy C10, reviewing the pix you attached to your earlier posting, I noted that you have not installed the cowl vent cover and related L/R cover pieces.
All three of these pieces are very tricky to install. Generally they install with the same flange head type of bolt as the fenders, etc. However, the alignment is very critical requiring fitment to the doors, etc., several 'horseshoe body shims are required to get the proper alignment to the body prior to installing the hood. Make sure you have the wiper transmission arms, etc., without the wiper arms, installed before installing the cowl cover. The hood bolts should be the same style, flange head, serrated as the fenders, however, they might be larger, I would have to check that out.
As I have mentioned earlier I have two 64-66 C10's that are partially disassembled. I just finished replacing the front-clip on one with a front-clip from a donor truck to eliminate rusted out components.
I bought a new '65 C-20 Camper Special. I ordered the factory manuals for the truck from GM. (there use to be an order form in the back of the owners manuals for same) Since the 63 -66 trucks are basically the same I received the '63 truck manual, a very thick manual covering the body, etc., I also received the 64-65-66 supplements, therefore I have a complete set of factory manuals. In 68 I bought a 68 K20 4x4, so I have the '67-68 factory manuals.
The factory manuals are very detailed, however, when it comes to fasteners, the various fasteners are generally shown, however, the sizes, etc., are not listed.
I would be glad to snap you pictures of any area of the '64-66 C10's that I have. Wm.
