Your shifter will work for this trans. If it's a 700r4 get a shift cable for a floor shift camaro of the 80's with a 700r4 and a bracket on the trans pan also. For the steering column if you have a stock setup it will work with the shifter. You can leave it alone unless you want it to indicate you have overdrive? If it has the stock computer and still functioning it will control the lockup you just need to ensure it is wires correctly.
