E-brake hardware mid-70's 10 by 2-1/2 drum

Getting back to putting my 64 Barracuda back together, after close to 10 years and two moves it's a bit overwhelming. Found every last piece to the 9 inch rear drums it had on it, and after looking and looking I found most of the 10 by 2-1/2 brakes I was going to put on. Missing are the e-brake spreader bars and levers, as well as the self adjuster stuff which I can do without. Being that there is no drive train in it having a parking brake would be good right now. soooo.... looking on line I can't seem to find these parts. Any ideas where i can find them? Thanks!
