67 Panhar bar

[rockb1]

Here is my current set up. I took 3x3 steel tube and ran it just above the frame from the second bed mount back. I boxed in the front portion of the frame, attached the 3x3 and cut the old rear section out. Its a very simple z'd frame but it sets the truck down nicely. I am running the stock trailing arms for now but need to replace the Panhard bar. What is a good option or set up?
I need ideas, photos, tech articles, something to help me out
