Re: Mystery parts.

Ditto, center support for grille, looks like a GMC, the Chevy's were different for each of the grille changes 67-8, 69-70 & 71-2. Could be wrong, going from memory (that's not saying much!)

top item in pic is the vacuum pod for the exhaust heat riser on pass side manifold.

Re: Mystery parts.

The top thing is an exhaust pulloff for a heat riser, but I don't think these trucks ever used them. I saw them on mid-70s Chevelles and Montes, that sort of thing.

It is also the support for the hood latch release on a GMC.

Precisely called the EFE valve (early fuel evaporation). Used all the way up into the mid 1980's but never in the early 1970's
