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.

Pulley - 2 Sheeve


Part Number: 11479
Retail Price: $42.00

Hi 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
