I would swap in a points diast in a jiffy

use the one keyed hot wire thats on the coil and add the black points wire to the coil

been do every elec mopar I have had in my life time

that was when an 75yr old man fixed mine on the side of the road one day....

I got one on the bench with new points if ya need it

and I still think 18-19-20 on tha vac gauge is were its gonna want to run ones you get this grimlin fixed

thats where I start,swap to points and tune with a vac gauge..has never failed yet
