4-rib belt?

[Garrison]

I have a stubby (space saver) M62 snout that I want to run, but it has a 4-rib pulley on it. Can I run a 4-rib belt in place of stock 5-rib?

Never mind, I disassembled the M62 just now to try and swap the snouts and the base for the new snout is too thick, it's definitely for the first gen m62s. Oh well.
