I bought a j2fab alternator some time ago with the provided pulley and the need to shim the alternator. A few months after i purchased the alternator i saw on facebook that they had came out with a direct replacement alternator pulley with no need of shimming the alternator. I have tried to get in contact with j2fab a few times through facebook and i get no response at all so i can purchase the pulley. Question is, how much of a hassle is to try and shim the alternators for those that have gone this route?
