Used parts, NLA parts, new parts... what do people NEED?

[Jonathan]

I think a lot of us have collections of used parts kicking around. Boxes and totes of them in the basement or corner of the garage. Plenty of for sale threads advertising used parts. Lots of similar stuff and a few odd ones in there too.

What I'm wondering is, what parts do people NEED?

What parts are you keeping an eye open for, but they aren't readily available? Either they're rare or NLA, or they are available but too expensive, or the part wasn't a good design and you're waiting for something better?

Just thought it might help other owners (and vendors) to understand what it is we're looking for and need to buy.

A couple things I'm in the market for are:

Crankshaft pulley (102469, originals are NLA, aluminum remakes available but pricey at over $400 CAD)
Driver's side bolster interior trim piece, black interior car (110171, NLA)
A/C fascia plastic base (108920, NLA)
Stainless steel auto trans dipstick tube (106770, not aware if these exist in stainless or not)
Catalytic converter heatshield (NLA and perhaps unnecessary?)
Oil filler plastic screen (102420)

I'd like to see those Momo steering wheels and special adapter kits become available again.

Matching front and rear tires in original sizes, frequently discussed elsewhere.

Top of engine block for anyone with block rot troubles?

Others?
