I'll assume you have a column shift now? If so yes there are brackets required along with various shifter parts etc...Did you see this? http://www.cuda-challenger.com/cc/index.php?topic=104266.0 Pricey but gives you an idea what you will need as far as the shifter goes. They do repop the required console brackets but they do come up used often as 4-5 speed conversions are popular.
There are two brackets that weld to the floor. Available from AMD . You could possible bond them with some panel adhesive in case you didn't want to weld
