I just did this on my 66 valiant. It was a daunting task. I would definitely recommend having the shifter installed to place the hump correctly. Also shift the shifter in all gears before attaching the hump to the floor to check clearance. Don’t ask me how I know that I’m still mentally scarred. I do have a hurst shifter handle and a bezel from a 65 barracuda I will not be using if I can acquire a console 4 speed shifter at a reasonable price. I found a console but the b-body shifter I have won’t work with the a body it hits the dash. The handle is an a body hurst with the t handle. I don’t have a pic n my phone.
