Replying to Fks question, again

So on one of my heel piece, the plastic part that hold the spring under the forward pressure indicator break and i lost the spring.

My turning table is now free to move back and forward. So i adjusted the two screw onto the arm to get my heel piec a bit more forward so when i click my boot nothings is able to move.

I know That wath i did is to put the forward pressure a incredibly high level and increase the risk of injury badly.

My questions is, Can i buy just the part of the binding that is broken or have i to buy new bindings ?
