The new belt you can get at any parts store, you just need to know what size to get.

Depending on the pulleys you get, you can run a string or something to get the approximate size you need. I believe the two piece March underdrive setup (Alternator/Crank) requires a 59 inch belt. SO you would need Dayco number 590K6.
590 = 59.0 inches k6=6 rib

If you just get the March crank pulley only, then I think its a 59.5 inch belt. So 595K6 would be the Dayco part number on that.
