How many 73 dual exhaust hangers do I need?

[WH23G3G]

I'm soon ordering the 73 400-4 dual exhaust kit. Does anyone have a photo of the driver's side floor pan bracket for the muffler hanger? Since mine was a 318 car I'm going to have to add the bracket. I need some reference as to where it goes. I've got the new passenger side muffler hanger, and I know I need the two tailpipe hangers on the end of the pipes. Is the floor pan bracket the only other holding the exhaust system up? I'm getting the Accurate kit. Do they go on pretty simple once all the brackets are in place?
