You have a sub plate that looks like it is a D03 size. Their mounting plate is pretty clever for getting it in there. Your entire system is sitting where I mounted a hydraulic "wiring loom" to guard the hydraulic lines and prevent them from getting into the HST pedal linkage.
My 3rd function requires three custom made plates, and four custom-length hoses just to plumb to the quick disconnects (not to mention the electrical harness that uses weatherpac electrical connectors) and is an order of magnitude higher in cost as a result.
Well, it is bolted down for sure. I guess what I am asking if the explanation and fix seem to make sense??
