Thanks guy. Got a Pertronix from Classic cuas I was there and they had one. Talked to there tech guy and he said all I had to worry about was getting the gap right. I put it in late last night. I'll get the distributor back in this weekend and let you know how it works. The instructions show to test the voltage to the coil and depending on your aplication make sure that you have a full 12v. If not then you may need to remove the resitor if it has one. I have not tested it yet but I think I don't. I'll let you know if it fires. Thanks for all the info as always. Thats what makes this form great.
