your favorite small block footbrake/bracket race torque converter
I will also add that when I drove my car on the street my dynamic verta never gave a sign of trouble but when raced at the track or on the street it did what it was suppose to do.. so the dynamic is a great all around verta that can race and drive with out a problem...been had my verta for about 12 yrs.. sent it back 1 time cause I changed combo and still works as was told..:D
