hey Alvin, I have a Jet 12x40 and a enco 10x24, I have found that the Jet BDB-1340A which parts are still available for from jet, fits both of these lathes, I have ordered the back gear from the 1340a and it fits my old enco lathe with just adding a couple of spacers on the shaft, I have also ordered several gears for my 12x40 and they fit perfect. you can down load the parts manual from jet, the parts will probably fit your lathe better than the grizzly stuff
