Guys I'm in need of a few gaskets, felt and vellumoid washers and I don't know where to get them. I need a PTO cover gasket (D1740R) which is not available from JD, Air cleaner gasket (D2377R) not available from JD, Shifter oil drip felt washer (D2098R) and Vellumoid Washers (D933R) and according to the parts manual I need 10 per rear axle quill bolt. There are eight axle quill bolts and these washers are 8.54 each from JD. When I removed all eight of the axle quill bolts only three still had any washers left. My question is are these really needed because I won't be pulling the 8 axle quill bolts on the left side of the tractor.
