The Stovebolt Site Forums The Parking Lot '60-'66 Trucks swap 3 on tree to floor shift -- questions

I'm having a lot of issues with the column shift linkage getting stuck. Would like to switch to a floor shift for the 3spd but could end up putting a M20 4spd in down the road. Does anyone know if there is a floor shift set up that would work with the 3spd and possibly the 4spd down the road?
