Grizzly G0477 parts

[Dale Dumond]

I bought a G0477 and have been pretty happy with it. But I need the idler sprocket and idler sprocket base and Grizzly no longer stocks these items. I talked to Grizzly tech support and they suggested that Bosch makes a "similar " planer. I can not find a Bosch thickness planer only their hand held ones. Anyone know what manufacturer is the same as Grizzly. I hate to trash this machine because I can not find a $20 part.
thanks for your help and Merry Christmas to all.
