Rusty,
I would venture a guess that if you know the particulars on your alternator (like what it came off of), the folks at Racing Beat can tell you over the phone if they have a suitable pulley with right shaft diam.
Just a theory .... Jim S.

Rusty, Racing Beat has a double pulley in aluminum and of a bit bigger size than stock to reduce alternator RPM. Should fix everything in one shot.

Rick GirardHi Rick,Do you know that the RB pulley has a 15mm hole for the shaft?  I may be running this exact pulley now (can't recall who I bought it from), and I know that I had to enlarge the hole, as well as make a spacer bushing to make it work on the FD alternator.  Does anyone have a 2nd gen alternator handy?  If so, can you measure the shaft diameter? Thanks,Rusty
