What year is the engine? Does it have tapered seat spark plugs with 5/8" hex or the long reach 13/16" hex plugs? Both have been covered at length if you care to use the search function.

No great upgrades for those. Stock type NGK or Denso is about all you can hope for. Autolite 26 is fine as long as they aren't Chinese.

...but since Autolites are Chinese (all of them, now), stick with NGK.

I run .045 on the NGk UR4's with an older chrome MSD Blaster 2 coil and using the MSD resistor that comes with the coil in place of the Mopar resistor. I read a full 10 volts at the coil at idle for a pretty healthy spark.

All mopars are .035... if you have the mopar EI, you can get away with .040 if everything is in good shape and you are using quality components (that autozone replacement coil is not it...).
