Pertronix Readjustment help.

[zombie66]

I've had the pertronix installed in my stock distributor for a few years and need to readjust the gap between the module inside and the round magnet. I lost the plastic gauge that origionally came with it so I picked up some brass feeler gauges to do the job. I just can't remember what the gap was supposed to be and the pertronix website did'nt say. Does anyone here remember what it was?

.030 gap, but i've heard not to use a metal feeler gauge for some reason.

Thanks for the gap size. I assumed its because the steel feeler are magnetic that's why I picked up the nonmagnetic brass gauges. It figures I would misplace the plastic gauge because I hang onto everything. But I will wait and see if anyone tells me the brass ones will work. I don't want to screw anything up.

Anyone know if there's a problem using brass feeler gauges for adjusting the pertronix gap?

Brass is fine.
Even steel ones will work you just have to make sure the gap is the gap and not the guage sticking to the magnet fooling you.

sounds good! Thanks for the help.

matchbook covers work great. also for adjusting point gaps. double it up and it works for spark plugs too!

I like the matchbook idea. I did figure if the brass feeler gauge option didnt pan out I'd need to start measuring peices of plastic for the right thickness. It does seem like every time you hit a roadblock there are some pretty ingenious ways around them. Thanks for the input.

X2 on matchbook cover works perfect!
