Snubber for Duster

I'm with you 12many, when I first started in Mopars & found out about pinion snubbers I threw away the old slapper bars. They have been proven to work many times over the last 50+ years.
All I need to really know is that Sox & Martin as well as the Ramchargers used them with great success up to a level of performance where the whole rear suspension had to become a totally different setup. I’ll never get to that point with my junk and don’t want to for that matter. If they could do it for the et’s they ran it’s good enough for me.
