Rear Suspension Question..

OK guys here's what I've got, my 70 Dart has Super Stock springs, I currently have Lakewood Traction bars on the car, and it's not hooking very good, I have been told that I need to use a pinion snubber by several Mopar friends. My question is should i use a snubber? And if so, should I remove the Traction bars, or leave them on and add the snubber. I put the bars on, an then learned that they were not the best option, I'm new to MOPARS and I'm looking for some advice from Mopar experts. The car has a 499" low deck 400" engine with a reverse manual valve body 727 and an 8 3/4 rear end with 4:10 gears.
