I would say that the shifter is an over the counter purchase. Someone will correct me here, but I do not remember ever seeing a Competition Plus shifter like you have from the factory in a Mopar. Do not remember seeing a bolt in shifter/handle either. I always thought that the shifter handle was a bayonet. So many people wanted the square handle lever over the round one, shifters got changed alot. The Competition Plus was built for abuse, the stops, changeable lever options and bushings for the shifter rods.
Hurst was only in Mopars for a few years, if it looks like a Hurst, but doesn't say it, my opinion, it's isn't a Hurst. Again, I may stand corrected on this!
