Tops were cake if the holes are good, just put in the new bushing & pin, the bottoms you can just use the pin if the holes are tight, to add the bushings you have to drill out the holes, I drilled one set, kinda awkward the way the bushings go in, so I did aniothe r(tight) set with just new pins.(oh yea, only drill the middle holes, not the outers! ) Rich.
