Need floor shifter to fit a New Process 3 speed w/ OD for 65 C10

I'm trying to put in a New Process 3 speed w/ OD tranny in my 65 Stepside but running into lots of problems. Current one finding a floor shift since I can't use the column shift and the manual OD. Any help on this much appreciated

 

go to youtube they might have some info .

 

Thanks but I've already tried that. This is a pretty specific and I think fairly rare application. I checked with a products specialist at Hurst and he says the 4 speed truck shift they have will fit the transmission ok but the linkage may take some fabrication. That could mean just about anything. And no way of knowing if that shifter will clear the stock seat without installing it and finding out. Guess I'll find out !
