Mine is factory system from handle to backing plates. I think it is the same as I have a 1966 K-10 Chevy Shortbed Stepside, just has shorter rear cables. Seems I just ordered them right off their list. I have the invoice and will list it tonite. The backing plate is Bendix so it is a standerd 2 bolt plate as it travels though to the E-arm inside the drum. Nice quality.
