I was just looking up the bushing part the other day. Here is the dimensions of the bushing:

Bushing; Bore=0.753", Outer Diameter=0.941", Width=0.88"

Rock auto has the best prices I have found for the bushings. As low as $1.23 for the Dorman #690005 upto $3.75 for the National PB286HD. Most other places are around $10?
