I'm new to this forum.  I am looking for some parts for a JD #71 sheller that I bought last summer at a sale.  I had been looking for one for several years in good shape to use for demonstrations at our county fair.  I am needing a couple of parts and was wondering if anyone has a parts unit.  There are a couple of things that I am in desperate need of.  The first is the gearbox that is toward the top of the clean grain elevator that runs the truck loading auger.  The other is a 3.5 inch auger tube for the returns auger.  It is about 5 feet long.  Also, if anyone has an extra drive belt hanging on the wall for one, I would be interested in having a spare.  It looks sort of like a wide serpentine belt. The sheller is really in excellent mechanical condition and good cosmetic condition for original paint.  I am hoping to have it up and going this summer for the fair.  Any help would be appreciated.  Please give me a call if you can help 765-427-3441.  Thanks, Jeff
