I wanted something that looked like a manual shift stick coming out of the floor having a 700R4, and found 'Gennie' shifters that is a bit different than 'Lokar' stuff.
Built a floor plate to fit around it. And have an old school accordion rubber boot to go around it.
The stock bench seat is going in.
With the trans that far back from the cab, a floor shifter with cable is going to be the only option, unless mechanical arms can be fabbed.
You could check with Gennie and Lokar to see what they offer for cable shifter options.
