Title pretty much says it all. can anyone help me out with some measurements for a trigger wheel. Im going to see if I can make my own but my pulley is on my car in Pennsylvania and I live in Maryland. and I cant make it up there that often. 
so if anyone  has one sitting around do you mind helping me out?
I need the thread diameter, pitch, size, and length of the crank bolt.  
I also need the depth of the pulley from the outter face of it down to the bottom part where the bolt meets the pulley. 
and last I need the diameter of the smallest part of the pulleys bowl also where the bolt meets. 
thanks guys
