Removing the linkage and doing that bushing on the bench makes it a bit easier. From some old postings, you rig sort of a threaded rod with nuts, washers and sockets to press in the bushing. The bushing on the drop down tang from the shifter requires a shorter rod but is done with the same principle. IIRC the bushings on my w124 were a PITA but the (green) ones on my W202 were softened in hot water and just pressed in by hand.
