Column shift bushings replaced on W111
 

I managed to complete this without the proper tools and little if any mechanical skill. It shifts nicely now and the reason why I embarked on this project - random horn honking - is cured. But now it is somewhat difficult to get into reverse. So, the question is, is there some sort of adjustment I can make assuming I put everything in correctly?

Congratulations. The problem getting into reverse is most likely the bushings on the transmission/shift linkage. It's pretty easy to change them with the car on a lift. The biggest issue - not really that big - will be getting the cotter pins out. The bushings are cheap and readily available.
