Barkbuster Spare Parts

Sorry if this is the wrong spot for this, but I recently tried to install some Barkbusters for my AT & ended up swapping Nm for Ft-lbs in the torque spec. That fun mistake means I snapped one of the 28.6mm clamps from the kit & am on the lookout for a replacement part.

I quickly realized there are no resellers in the US for this part (at least that I have seen) & was wondering if anyone knew where I might be able to find a replacement.

Thanks!
