My conversion is using an original 9146 case. I am using a 911 fan housing and 55amp Bosch Alternator. I have assembled and I'm not sure if I have a problem. See pics. Belt doesnt seem to align properly. I have 5 shims under and 1 shim on the outside. I'm wondering if the housing that I'm using may be a problem as it is from a later model car. Housing number is 930106102OR and you can see it on the second pic.

I'm using my orignal six fan housing # 901 106 101 5R. I upgraded to a larger amp alt. and my alt. stuck out too far. The opposite of your problem. I checked another six fan housing and it was deeper in the mounting area than mine. To make the new alt. work, I had my housing machined down to match the other fan housing and that made it right. It is being used on a 3.0 built on a 930/68 case (3.3 turbo). You may have to find the right fan housing or another alt. to line up the belt correctly..... a pic of my housing after it was turned down....
