I went with the Patrick Motorsports single pulley conversion when i installed my 3.6 engine and it requires a single Contitech belt which is available at most local auto parts stores !
I've done close to a dozen track days and i had to remove one shim at one point but i guess it was just normal belt stretch,best part is that spare belts are only $7.00 !

Cheers
