byoffcr,
Your 1/2 correct. There is no problem using this on the 9-Tower clutch, but there are some reservations about using this on the 6-Tower. I have read on this board, people using it on the Cat 6-Tower though.
Sabercatt, I have a heelclicker setup that has about 700 miles on the weights, all of the hardware and springs, in the original box. I will sell for 1/2 the cost of a new kit, let me know.
