I would think about a hinge-pin-brace type piece running between the front camber link mounts, right behind the ball ends. It may be pretty easy to torque those (very clever) extended ball ends out of whack otherwise. Just a thought.
I see McMaster Carr's MXL and XL timing belt pulleys are cheap enough (<$10) that you could buy a couple that may not fit, but would be a jumping off point for ol' Seabass...
