Greg/Wolfgang: Pretty sure this hinge is for a Spyder trunk, since we're in the Spyder section. A 356 hinge won't work, the hinge has to have a larger radius as the front trunk opens further(90 degrees plus).
The original Upland CA produced Becks had no hinge at all. You removed the lid completely for access. So this hinge that isn't pretty is comparably a major improvement. Vintage Motorcars makes a tubular curved hinge, but the steel plate in the Beck may not be compatible. At the very least, new holes would have to be drilled and tapped. Maybe more surgery than that would be needed to make it work.
Personally, while it isn't the prettiest, it works, and it's already there. I'd leave it alone.
That's the problem, it doesn't "work." It only opens far enough to get vertical, and the slightest breeze or bump has it falling closed and because of the slop in it, it often catches the fuel cap on the way down. Luckily, I haven't chipped the opening in the hood, yet, but I want a real hinge before I do.
This "hinge" was obviously home built by the original builder, but my hood does have three nutserts left and right that weren't utilized. (My guess is they were on the turnkey versions)
Im pretty sure I've spoken with both Greg and Carey about it, and neither believed their hinges would work. I'm looking more for a hot rod solution that might work.
