I just voted. Allowing aftermarket has a slight lead @ 82%.
Cars that use strut rods:
All AMC
All Ford
All Mercury
All Plymouth
All Dodge
All Chrysler
To be fair, that would probably be all those built before 1974. Probably a very small percentage of the stockers use a strut-rod suspension system. I mean, how many AMC, Ford, Mercury, Plymouth, Dodge & Chryslers race in Stock? Can't be but a small portion of Stock. Right?

And as NHRA can see, only a very few amount of racers need to be unsafe to make the other racers happy.
