Well thats a relief....I've got it in my head I "NEED" an exterminater. I knew they they had value, but when I saw that price the other day I thought my dreams of Rathmann Glory were CRUSHED!! That and the fact that at that price I could get..........oh lets say........somthing like a used 911. A ni...

What is up w/ this? Isn't that a "little High"?

My ears love it...It is music to my ears.

Steve, My camera is not working. The diaphram has 2 cardboard/Paper sides w the diaphram material sandwiched inbetween. It has a metal plate on each side of the diaphram material w/ a rivet in the middle. one of the plates has a series of holes in a circle. my old diaphram is the same. I can take it...

okay I got a champion l78c's from the parts store the c stands for copper.
Did not have just a L78 or a autolite 411
Crossed the champion plug to a NGK B7HS
so I bought the one champ. plug they had and got 2 NGK's
What should I gap them at?

older 91b1's or just mac's in general?
