Roto-Hydramatic 10 (slim jim) shifter?

hey there hambers im building a 39 pontiac with a 394 olds and the slim jim im looking for a floor shifter that will work with the slim jim any ideas guys

 

I once made a B&M Uni-Matic fit my old hydro... I filed the gate so you had to pull the shifter up in order to get reverse..

You could do the same with the B&M Z-Matic and have a better shifter..

 

I would think the stock floor shifter should work from a console car?
