grain drill parts

[paige kirkland]

Trying to build some grain drill type implements, and having trouble finding new seed cups,seed gears, and other basic parts that can be bought reasonable. I'm looking at buying these parts 50-100 at a time. Is there any place that you can buy these in bulk to save on cost.
Thanks

Might try Shoup Manufacturing. Didn't see seed cups online but try calling. They are an aftermarket equipment parts supplier.
