I purchased the whole setup from Don and never could get it to work. After a bunch of headache i gave up put on pertronix unit and eliminated box,wiring, ect., just to find out that the coil from fbo was the problem the whole time.
Box is good!
I think i will just keep the pertronix now that it is installed and running strong.
If anyone wants to buy the setup off me i will be willing to take offers
