Can someone with a big enough calipers measure a factory smog pump pulley for me? My calipers don’t reach in far enough. Measure to the top of the ribs.
 
Ill try to get the measurements for you tonight after work. You want on top outer edge of pulley or ribs where belt rides? Just to verify.
 
Top of the ridges where the belt rides. My guess without the proper tools is around 5.36”
