Automatic transmission on the floor

Kinda rare to see a floor shift 73+ swinger but its not a problem to add it. Your floor pan will already have the dimples to locate the hole for the shift rod and boot. It should also have dimples to locate the console brackets.
You do not have to change the transmission. You do need to look at the tailshaft and make sure it has the two bosses coming off it. This is where your linkage bracket mounts to. Early cars did not have the ears and truck transmissions did not have them either as far as I know. At some point they started putting them on all of them....at least on the cars.
Dont forget, you will also have to change out the collars on the steering column. Tony D. sells the collars. www.tonysparts.com
