| Have used St. John's bars and concaves for over 25 years and never had a problem. They have outlasted chrome bars by 30% or more. Can I use these folks for replacement parts on the rotor system of a 7860 and if so how are they performing compared to originals? Just traded for a rotary with 400 hrs and am a little aprehensive as to what the learning curve will entail. No more walker machines,,,,, don't know if that is bad or good. | |
