After feeling successful with the hinge install I couldn't resist at least bolting what sheetmetal I do have on the truck. So the battery tray and core support got slapped together and the left front fender got bolted on.
And that brings this thread to where I am now, waiting on right front fender and core support mounting kit. I have a long way to go, probably take years but I'm happy to have my old truck back and be turning wrenches on an old C-10.
