Simple, and possibly dumb question!
I'm refitting all the parts to my car after doing an intake manifold gasket change. While everything was apart, I cleaned everything and in some cases repainted parts too. Even though I photographed much of the strip down, many of the fasteners are now so clean it's not always clear where they used to be, no tale tell marks to match them to!
I have managed to work out where most parts and fasteners go, except for one bolt. I *think* it came from the inlet manifold, as the only empty bolt hole I could find was to the left of the number "5" of the intake manifold, driver's side, just below the carburetor throttle linkages (see pic below). It's not one of the manifold to head bolts, but it looks like it might have been used to mount something. The mirrored bolt at the front end of the manifold, to the right of number "3" is used to hold the AC compressor brace bar.
Is this bolt next to number "5" simply screwed into the manifold and not used? I can't for the life of me work out what is supposed to be bolted there.
