GA WTB: Inline 6 engine parts, also "250" grille emblem

[79 silverado]

Specifically need the following, cheaper the better:

All the front accessory brackets: alternator, power steering pump, air conditioning (rare I know). Also would need any pulleys, etc for same.

I picked up a NOS crate 250 inline six from a gm dealer and I'm going to swap it into place of the annoying 350 the truck came with that I hate/loathe. Needless to say it doesn't come with any of this stuff and I'd rather not deal with having to drag home a donor engine off craigslist to grab the stuff off of if I don't have to.

The carb/alternator/distributor I plan on buying new unless someone has an almost new unit lying around they would like to part with.

Anything else you may have that could be of use in the swap, just let me know!
