My 65 Barracuda has 235-60-15's all the way around. It's a pretty tight fit in the rear wheel wells but doesn't hit or rub and I'm running standard shocks (no air shocks) On the front it also is a close fit but again it doesn't rub and has standard hydraulic shocks.
As for the "green bearings" those are for an 8-3/4 rear end so you do can do away with the adjuster on the right side axle
