NormK, for a rh intake in a VC 160/125/Auto Drive base you would need to bore two portals through the base itself for the tube to pass through and put a sheath around the section that is inside to shield it from the high speed clippings and other debris on it's way to the catcher. It may interfere with the flow as well. I think it's best to keep the air hose to the left on these.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
