It came with a new hat and then this circular metal "coin". It was SUPPOSSED to come with instructions but none included and no response back yet from them. What is with the coin?

The adjustment screw pushes against the coin.

I put one of those on my '85, the coin is just a washer for the screw to press onto as you screw it down, it sits on top of the diaphram assembly, i ended up leaving mine off because the bolt was too long and hit the plenum, it works fine without it.
the reason i used a longer one was because i wanted to use a lock nut on the bolt, just for info the afpr held pressure longer with the lock nut in place.
