Powerbond under drive pulley. Scoggin Dickey has them for $199.99 & includes what appears to be an ARP bolt & both belts. The ALT pulley is separate, about $30

Srsly? Look to the right of your screen & you'll see a box that says SDPC. I got my UDP from them. I bought the ALT pulley from Summit. You can tell Scoggin Dickey that you want a specific part # for the belt. The belt part #s/lengths can be found on Thunder Racing.com's website. The A/C belt is a certain size, the serpentine belt length depends on whether you are running the ALT pulley or not. I think without the ALT pulley, I ran 14.2 volts, once I changed the ALT pulley, it went back up to 14.4 volts.
