|You could do to both of your trucks what I did to the rear trucks on my skates; and it would most likely solve your problem.
I bolted the trucks to the skis with short bolts. Then, with strong clamps holding the plates to my boots, I drilled 2 more holes through the trucks and on through the boot. These 2 holes required 2 long bolts to attach the plates to the heels of my boot. You could do the same to your front trucks.
Note : I would not put a bolt anywhere where the sole of your boot is not touching (as in your picture) the plate. It might cause the bolt to pull through.
