If there's one thing I'd put on my wishlist it would be better bushings for the caster blocks. They seem to have quite a bit of play in them, especially after a hit or two. What I've been doing is driving a wood screw through the hole in the caster block to give it a bit of a tooth, then putting a little shoe goo around the outside of the bushing to hold it in and eliminate the slop. It works well but a better fitting bushing would be a lot less work. Happens on the top at the ballstud and at the bottom with the screw. Just the slightest bit of slop introduces quite a bit slop into the toe and camber. And don't get me started on the bushings for the steering rack...
