Greetings,
 
I'm using the fairly standard little ND 55A alternator, which has a 15mm shaft.  It comes with a single sheave pulley, and I've always planned to change that to a dual pulley.  At one point, I found that the stock Mazda alt had a 15mm shaft, so I ordered one of the dual pulleys from Racing Beat.  Since I had the alt off, I decided to install the new pulley, but after much effort to get the old one off, I found the new one won't work, so I'm back to my single belt pulley again.  The hole was the right size, but the rear side of the pulley needs to be flat, and the Racing Beat pulley is dished on the rear side. 
 
Is anyone running a dual pulley on one of these?  If so, where did you get it? 
 
The engine is installed again, as well as the redrive, radiators, intake, and exhaust.  I also stepped down to the 38 lb/hr injectors, rather than the 50 lb/hr injectors I was using.  If these turn out to be too small, someone will pay :-)  Still got a long way to go.
 
Rusty
