66 rear axle, sway bar, suspension questions

[msg]

I am not that familiar with the mechanics of the truck I have dismantled for restoration, just trying to take it apart and make it nicer as I get to putting things back. Im not wanting to do anything all that tricky just put it back but where I can improve things I will. The inclusion of sway bars has been an interest but Im unsure of which type to purchase and what may need modification. There is also a trac bar that was on the truck that needs a replacement I think. The rubber bushings in the trac bar are all dry rotted and cracked and I didnt know if the type of bar I have is something to replace entirely or replace bushings on it. Ill post a pic of what it looked like before the tear down.

So is there a sway bar recommendation anyone has for this 66?
And is the trac bar I have replaceable?
