a) What are the made out of?
b) How do they mount?

Looking good!

The golden spacers are 3D printed. It's a resource my team has readily available to us, so we like to use it every once in a while. They're a bit large in this photo. In the latest iteration they've been slimmed down to 1/2" OD (I think they're like 3/4" OD here). There are bolts (not put into the model until a later iteration done this morning) that go through the spacers and hold the plate steady to the frame. The new smaller iteration doesn't interfere with the gusset plates.

Two 9mm VEXpro HTD timing belt pulleys fit perfectly into the WCP WCD single and dual speed transmissions - they were designed to fit them perfectly, and my earlier design used two next to each other no problem with 0 interference. However what I like to do is put a single 15mm pulley in place of the two 9mm pulleys. The actual 15mm pulley is toleranced a bit larger than 15mm to be able to hold two 9mm belts if needed.
