82-86 are supposed to be the same (except for the 86s with a Dana 44).

I keep seeing reference in some of my books to the air pump ,and the air pump piping that injects air into the exhaust ports on the manifold, but I've never seen one on the 258. Not sure if it was ever there, or not, or what years, but it may impact the parts you listed.

It's for a 304? 304 wasn't even available in 84!
