Just going on some of the items I can see...
Losi steering bellcranks, Andy's front A-arms, Bud's bi-level wing, Proline wheels, Imex tires (on backwards), Composite Craft nose plate, Robart speedo, Thorp turnbuckles, Checkpoint Platinum mod motor (+ Reedy stock motor), a LOT of Hot Trick red, a few Associated suspension components, and that funny looking Tamiya thing bolted to the back. How's that?
I'll throw my usual disagreement with Jay on the Hot Trick stuff.

Back on race day in the 80s, Hot Trick was the Pep Boys/Cheez Whiz of R/C car parts. They may have been mainstream available, but you NEVER saw any RED parts in the A-mains, anywhere I ever raced (not that I was ever
in a lot of A-mains in the 80s).
The quality was marginal, fit and finish was spotty, the ideas were stolen from other companies, the aluminum was very "bending brake" oriented (like Sassy Chassis items) and the fiberglass components were kind of weak. My brother had a whole chassis conversion from HT because it was all he could afford—it was a low cost alternative to graphite components. It was a decent car, but Hot Trick was a low-buck mod buffet for the RC10 and other cars of the time.
Not knocking what people like now, it just was the punchline for jokes back then, and it makes me smile when I hear how coveted these pieces are today. No argument with the current popularity and value, though. I think the look is what so many people love, and it was SO different from the stock RC10 items. It could be the plain and simple fact that few of those pieces were ever really used in anger that might be contributing to the rarity of the parts. They always filled the close-out bins at any hobby shops I ever went into. If I had known then...

[Well, if I had known then what I know now, I would have bought as many sets of Tecnacraft wheels as I could afford and hoarded them away.

Parma, Bolink, Dahms and a lot of other companies were known for producing a lot of cheese, too, but they don't seem to have risen quite to the vintage cult status of Hot Trick parts.
Just remember... that's just one guy's opinion.
