Oh yeah, Mark brought up something I didn't mention... you can keep the same pulleys, but will just have one belt missing... and an extra groove.
I still have my system too, just tucked away and will never use, but it's still kool to have all the original parts. If either of you get's rid of the parts, let me know, I'd be interested... why? No idea... but like to hang on to that kind of stuff...
