Q: what kind of mounting hardware is included?

No hardware included, you use the original bolt an washer to secured it.

Q: How many ribs does this pulley have?

For a pulley it is the grooves that are important. The belts are ribbed and must fit exactly into to pulley grooves. This Pulley 38009 has 6 grooves. So the Belt should have 6 Ribs. NOTE: this Amazon page shows three times related: this 6 grooves pulley 38009, a smooth pulley, and a ribbed drive belt. BUT this drive Belt shown is a 4 Ribbed Belt (4K378, first digit 4 being number of belt ribs). Thus this Pulley 38009 does not match shown belt 4K378. So this could confuse the casual Customer. Recommend Verify every part correctness yourself before any purchase.
