So like a million other people on the planet I have been going round and round trying to figure out the proper distributor gear to get. I have a billet cam but it's made from 5150 steel not 8620. I don't want to use a bronze gear. thinking melonite one or composite. I trust real world advice on this one over the cam and distributor makers. I have a pertronix dist. Also! I pulled the gear off may dizzy and the shaft is made a little small. The gear slid off easy. Anyone come across that? I might center punch it to raise the diameter where the gear rides.
