I hade a broken gear in the oil pump, (1956 311, 148 ci. gas engine).
I am having a used oil pump shipped to me for $165+UPS from St. Johns Hardware, (Spokane, WA) 509-236-2282.
Also, The local case dealer can order the non-drive pump gear for $60. I considered buying two and having one machined for the spline but decided on the used one instead.
I am still looking the sliding sheetmetal covers for the hood and the Case hood emblem.
