I put the mock-up pulleys on my spare motor (along with the 62mm sc pulley).

alll in all, I like the amount of wrap. I need to change the smooth-flanged pulley so that it can accept the factory bracket (and then put less load on the SC casting). The Underdrive alt pulley in the pic is one I made for my other SLK32 (with a 181) so it is larger than the current underdrive pulley I am making)
