In the early 70s Stephen Pontiac raced in pro stock they had added TA parts on the forums they raced. It was deemed legal because the parts were considered a dealer installed option Idk that it answers the question but it was done enough that NHRA allowed it
Go to pintrest search Stephen Pontiac you’ll see the car
