Transmission Safety What Fits

If he's going to run his car at a NHRA race trank, an approved shield or blanket is required. One would have to check the rule book to find out what class it is mandatory for. Most racers I've know over the years, had some sort of protection, no matter what class/speed they ran. It makes no difference to the NHRA if your transmission is the $$$$ unit or a stock unit, a shield of some sort is needed.
