Help/info with '70 Dart exhaust tips & hangers

I'd like to add the '70 style exhaust tips and hangers to my '71 Dart GT.

I currently have 2 1/4" pipes to the rear bumper with an angle cut.

Where would you buy them from? I believe I've seen 2 different length tips. Which length should be used? Also, based on the pictures I've seen of the exhaust tips there are probably specific hangers that must be used. Can anyone post pictures of the hangers & mounting locations?

As always, thanks for any input/direction!
