Uses 7/16" rod ends from Pegasus Racing. Bottom bracket is actually a lumber tie from Home Depot. It's a skosh thin looking, but doesn't seem to deflect noticeably -- the stress on it is almost all vertical. I reworked the piece a fair amount.
Note that the end links are length adjustable with a lock nut.
I also have collar clamps around the sway bar at the bushings to stop any side-to-side movement -- I found it would work itself from side to side and bind up. This might not occur with rubber bushings.
