Finishing up re-wiring my 66 Satellite and going from electronic distributor/MSD box back to factory dual point (not an MSD fan). My coil is non-descript - had a few signs of being at least part red and painted black. But no identifying marks or labels other than #1104 stamped in the bottom which I haven’t been able to match up with anything including MSD coil part numbers which seem to start with an 8. Maybe an old Mallory. Probably very old. I’ll probably run it for awhile but would like to have a good quality backup in my parts drawer. Can anyone recommend what passes for a quality coil these days for a standard ignition system? SMP? NGK? MP?
