Hey Sam! That same binding blew apart on me two winters ago while hiking into a yurt for a much-anticipated long weekend. At the time, I too was a college kid just trying to save some money, and I too posted pictures of the broken parts here on Skimo Co asking for help, so I understand the struggle! I ended up just buying a new Speed Turn 2.0 heel for $90, but your breakdown is different. It looks like you can get away with buying a Speed Radical Heel Base, which is a cheaper fix. Happy skiing!
