Urethane Bus Beam bushings

Urethane beam bushings.  These newer bushings are a much harder material than the old style squishy squeaky red urethane.  I like to use lots of synthetic waterproof wheel bearing grease meant for boat trailers with these.  These fit the tubing and the arms nicely, and do not grab the arm or pinch anywhere. 

The later '64-'67 style do not fit correctly from the manufacturer.  I have a mandrel, and I machine the early bushings to fit the larger sleeve on the later arms.  The '64-'67 bushings are a little more money because of the extra machine work needed.
