Pertronix Electronic Ignition model #?

[John - NNY]

Anyone know what model number Pertronix Electronic ignitions system works in a stock model A distributor? I am also looking to buy one of those automatic spark advance gadgets that replaces the lower distributor shaft. Anyone have experience with those?

I found one of these in my dads stuff and might use it on my AA. the guys on the Ahooga web site say they are great if everything is hooked up right . You can't use a pop out switch though.

i have a petronix in my A utility. i purchased mine through
FS ignitions
i would swear by them now unless you want the original pop out
my Utility has more power now than it ever had with points.
Iam very Happy
