Magnum Swap column vs. console shift
The shifter will probably be the least of your headaches as far as the transmission goes. You can mount a Hurst or B&M ratchet shifter in the console, and it will look almost stock if you choose the right one. The worst part is going to be getting the 46RE to clear the transmission/torsion bar cross member. The OD part of the transmission is bigger then the hole it needs to occupy, so some fab work will be needed. You will also have to beat the pinch weld in the transmission tunnel flat so it will clear the bellhousing part of the transmission. You can make it work, with perseverance and imagination....so don't give up!
