Pep Boys Crag is a bit nondescript, but is just south of the distinctive Milepost which sits right next to the road (west side). It's sort of small and blobby, and doesn't look like there would be any routes.
There are rap bolts near the top of Fingertrip Traverse of Josh, and a walk off towards the southeast.
