Which Pertronix for Delco Window Distributor?

Want to do a Pertronix conversion for the converted single-points GM Delco window distributor on a flathead, but I don't know the original application for the distributor - does it matter? Anyone know which kit to use by p/n?

TIA

 

I'd say 57 & up Chevy would be your best bet. Also I'd look for a CRANE kit. I have one in my 64 Catalina for 6yrs now, has a built in Adj. rev limiter. Have heard of alot of failures of pertronix units, I still carry a set of Points & conc. in G/box just in case!!! Pete

 

'57-'74 I believe.
