I am looking for a hydraulic piping section for a 645B wheel loader. Piping section T-73169, item 4, part numbers 73045819, 70923664, 70921117, 70916197, 70904207. These part numbers are from page 203 in the Allis Chalmers parts manual (revised November 1979). If anyone can supply this or knows of a dealer I can get it from, it would be greatly appreciated
