1969 square cooling fan motor fixed. control arm bushing replacement

Just wanted to thank everyone who replied to my previous post regarding the s-2 cooling fan motor question. After buying two fans from CoolCat industries I decided to check my faulty fan further and found that the coil wires had come loose at the commutator. I soldered the loose wires lubed everything and the motor is fine. Just passing this on for anyone else having issues with these original fan motors. Now if someone can tell me the procedure for installing lower control arm bushings I would be very grateful. Thanks John.
