I got mine from Summit racing for $119. Their address is

Powermaster sends both belts. Pa-performance sells the 3G alternators with one wire setup also available.
Aren't you the guy with a wiring harness problem also. Did you get one installed yet?
I replaced mine a few weeks ago and everything works again! It's not as hard a job to do as it seems.
I hope my info helps you out. Let me know if you want to know anything alse. I am expecting the alternator to arrive Monday or Tuesday and I can let you know how it works and how the installation went.
