I watched the bushings get replaced on my car, and they used some long tools with ends that looked like oversized dental picks to get the old ones off and new ones on.

I purchased the special tool for about $20.00. The shifter is easy to do from underneath. For the transmission I removed the sift arm.

For the transmission I removed the sift arm.
When he said that, an experience I had on the 300D came to mind that I should pass along, since the transmission and linkage is identical to that on the R107 (at least on the 380SL with the 722.3xx.)

The linkage at the transmission can be removed easily as there is a 10mm bolt that forces the end of the selector arm closed on a shaft that extends from the tranny. The shaft from the transmission passes through the center of the neutral safety switch and the plastic arm of the NSS is indexed by the center of the selector arm. If you are not paying attention or can't see what you are doing (or both) it is possible to replace the steel arm on the shaft and miss catching the NSS arm. If you do this , when you shift you can break the arm, necessitating a replacement ( and adjustment to ) the NSS. So be careful...

ps. That said, the OP has a 450SL which probably has a 722.1xx (4 bolt) transmission which probably has a different NSS lashup (metal). I think the 560SL has the 722.3xx but may or may not have the same plastic NSS.
