Try a website such as TSC (Tractor Supply Co.) and search for a starter switch for an N-series Ford tractor. (9N, 3N or 8N) It can be mounted to the floor in the position the foot start linkage would normally occupy, and the original pedal button can be adapted to the switch and covered up by the OEM rubber pedal accordion. It's very hard to tell it from the original mechanical linkage without a close inspection.
