Adjustable pinion snubbers?

mguner, weld a piece of flat plate to the floorpan at the contact area to both reinforce and strenghten the contact area and to distribute the load.

Yeah the factory "reinforcement" / snubber stop was originally located for the 8.25 so part of that issue is on me for not upgrading the contact pad and position. It's kinda hard to estimate spring wrap and contact point. I had about 2" clearance with a slight down angle. Big block automatic torque monster.
