Opinion on Electronic ignition for 68 340

I tried petronix, the distributor kit failed & left me stranded an hour from home.

So I swapped in a new unit from Dodge, all good.

Then the Petronix coil failed & it left me stranded again......

Original 50 year old coil back in & all has been well since. :)
After I ran MSD, I kept a points distributor in the trunk. I did that AFTER the 2nd 6A box failed on me and I switched to Mallory. I never had to use it but I felt better with it in the repair box. It recon' it would be about a <15 minute swap out on side of road with one wrench.
