The only real wear spot would be the ball and socket, are those any different in size compared to the smaller diameter ones?
No. Same ball and socket.
The diameter of the solid male threaded part of the 11/16" tie rod is thicker. But IMHO the hollow rolled adjuster with open slot is weaker than the Tie Rods.
True, I imagine the best bang for your buck would be a solid adjuster rather than up-sizing to 11/16"
The adjusters in my 51 Plymouth are a solid tube, not rolled, from the factory.
