What is the smallest OEM crank pulley I can get for my 96 LS motor?

reason I ask is my crank pulley sometimes rubs my radius rod in my crx. It's the middle pulley(either AC or PS pulley?) that rubs. So I need a crank pulley that has the smallest diameter for that middle pulley.

 

Use a GS-R or ITR. The AC and alternator pulleys are the same size for each pulley with the ITR having the smaller diameter, compared to a non-VTEC B-pulley that has a larger AC pulley over the alternator pulley.

what about a N1 pulley? small, light, OEM

 

i want a pulley with a dampener....if I switched over to a smaller pulley, would I still be able to set the timing right with the marks on the smaller pulley?
