I simply used my dremel with a small sanding drum attachment to get a little more clearance (or rather a little less interference). Spent maybe 15min on this, otherwise it was a bolt in for me.

just my $0.02 ... I found I only had to do some minor filing, more like finish work for the casting. I was able to use an SC for reference on the fitment. I spent most of effort on aligning the alternator, making sure it did not bind, spun freely and the blades on the fan did not make contact with the new housing.

I put over 1500 miles on the car before I sold it . I made sure the new owner was aware of everything I had worked on. He is a tinkerer (sp?) and has owned 911 before. He drops me a line every now and then to let me know where he has driven or what he has worked on.

Last comment ... I found the Conti belts "stiffer" than the OE Porsche belts. The OE belts fit better around small radius the pulley. I used the Conti belts for backup. I am not sure it makes much difference just an observation.

Once again thanks to the this forum ... guys like Iceman, ED and Rusnak have been big help with suggestions and information.
