Wanderer,
I have a 59 TF truck ,so it is not the same as yours but some info that may help you.
One of the pipes is the same as the original exhaust pipe. The other was just an 18inch piece of 2 inch pipe that I got from a shop with a flange on it, then I got a couple of 90deg. bends and some straight pipe from flaps, 2 cherry bombs and I was good to go. Later had a shop go over the rearend with it.
Hope that helps.
