Has anyone had any problems installing this TCI trans shield.

I would run all of the protection I could get. Years back when my partner and I ran Super Gas, we ran both. Luckily we only grenaded one transmission and the floor board need hust a little patching, it could have been a "LOT" worse.
Does the flex plate shield need to be 40.1 nhra compliant. I just don’t want to cut up my floors in my car. Or should I send the shields back to TCI and just get the 40.1 nhra legal blankets? And if I do cut out a section of my floor to make them fit what do I need to make that nhra compliant.
