Some of my family still uses Spademan bindings. It would be basically impossible to find a ski shop to mount your Spademan boot plates or bindings in this day and age. If you go to an old family owned ski shop you might find an old Spademan mounting jig or template, and if you are lucky, they might sell it to you. The bottom of the boot needs to be flat and thick enough to retain the screws. If not, alterations need to be made and/or a retaining plate needs to be installed inside the boot to securely keep the boot plate screws from loosening or pulling out upon release. There all also some boot to binding adjustments that need to be made correctly for the system (binding) to function properly. The bindings need to be lubed with a non water base silicon grease. If it is water base lube or the binding is not lubed at all, water can freeze the inner mechanism -- if it is cold enough, and the binding may not release. It is a good idea to clean the inner parts before you lube them. It was not rocket science to mount these bindings, But it would be best to find someone who mounted lots of them, back in the day, and see if they will do it for you. Good luck!
