When I did this on the 123, the problem was driving out the lower bushing. I did it by buying a long brass rod, 1/8th inch by 2 feet. From above the engine, I fed the long brass rod through the engine compartment and into the top of the idle arm assembly. Use a hammer on the top of the rod to apply blows to the idle arm bushing from above. This took a few blows and the bushing came out. The upper bushing can be punched out from below with a brass punch. Use brass so you dont put any scratches in the idle arm housing. Brass will not scratch or mark the steel, it is softer that steel.
