Been there done that!
I converted my '36 Ford coupe "Henry" from the original floor shift to a column shift shortly after buying the car in 1952. The transmission modification was a no brainer, I purchased a '41 donor car for the brakes, transmission. etc.
I used the linkage etc. from the '41, adapting the shift control box to the '36 column. I used the '41 steering drop, with slight modifications to attach the modified column, securing the upper part of the shift rod with a make do adapter at the top of the column, just below the Banjo steering wheel. This modification proved to be an ongoing problem.

I converted the headlight from the original reflector type to '40 Chevy headlight pods that I scribe fitted to the fender well adjacent to the grille shell. At the time, 1952. this custom modification was referred to as "The San Francisco Look". I also put '37 DeSoto bumpers on the car to complete the SF look.
Look closely at my AVATAR, the Chevy headlight are very noticeable!

The '40 Chevy headlights were sealed beams so a modification to the wiring was in order. I rewired the headlights incorporating a GM headlight relay into the system which allowed the column mounted switch to only control the power to the relay in lieu of the entire headlight system.
Within a few months the original headlight switch proved to be a big problem as was the make-do adapter for the shift column.
I eliminated the original off/on switch in-favor of a pull switch that I mounted in the original hand throttle opening in the dash.
I eliminated the foot mounted starter switch, utilizing a push button mounted into the left side of the dash to control the remote mounted solenoid mounted above the starter on the right side of the firewall. Uilized the hole in the floor between the brake and clutch for the dimmer switch. A perfect place for the dimmer. The horn hook up became a problem... Oh well, instead of honking at the girls, I could rev up the engine with a blast from the Smitty's.
Within a year the '36 steering gears became a big problem, and the shift attachment rod was a constant problem.
In 1954 a friend gave me a perfect '40 Ford steering gear assembly with the '40 column mass jacket. Fortunately my friend had the '40 parts car so I harvested the frame mount.
The '40 steering gear box went right into my car, only requiring a slight modification to the lower edge of the dash and elimination of the steering lock retainer from the steering shaft that allow and adjustment to the 40 column drop. Since the steering shaft was hollow the horn wire could be hooked up. The 36 pitman arm proved to be a problem, it hung down below the steering gears, as did the '40 pitman arm. It was not until several years later that I discovered the a 21-A 3590-3 015 (47 Ford) fit perfectly.
The Banjo steering wheel presented a problem, it would not mount to the '40 column.
I looked around, finding a perfect '47 Deluxe steering wheel. The '47 Ford steering wheel looks very good in the car. I still have the Banjo wheel and a spare '36 column, maybe some day I'll find a way to put the Banjo wheel back into "Henry". I have two '39 transmission in stock, that would be an easy way to get "Henry's' Banjo wheel back into the car.
