They seem similar to an IH type of shank. Jonathan Beiler at Cross roads cultivators will have IH type shanks in stock. I have his newest phone and address somewhere.

The other place to try is Roeters in Grant, MI. They have lots of Planet Jr. and old vegetable equipment in their boneyard. http://www.roetersfarmequipment.com/ You won’t find what you want on their website, but call and ask, if they don’t have any shanks in their building you will have to wait until the spring thaw allows them access to the back lot. When we went out the HPD 2012, we stopped here on the way home, it was our version of “antiquing.”
