Proform Adjustable Pinion Snubber

Mine was set at 1/2" and pounded the floor up so I had to pound it back down and weld a plate over it on the inside. It would carry the left front wheel most of the way through first gear.
Mine may have also. I was diligent on Maintenance on my car and inspected it regularly. But I don't think I ever thought to inspect the floor board!
