I absolutely despise them stinkin' hydrolic switches myself. I cobbled up a mechanical switch bracket for my 1800 that fit under the dash... easy enough.

My Jag has pedals more similar to the 544, and for that, I mounted a mechanical switch on the firewall under the hood.

I don't remember exactly how the 544/210 is set up, but I would expect if you follow the linkage along the way, you should be able to easily find a place where you could do it...
