Rich, I also have a 1982 500SL. Does yours have Euro Bumpers? I am looking for help in converting back to Euro from US bumpers. Have the bumpers, not sure on the mounting. Picture of the mounting point would help. Thanks

My speedo is electronic. Also was reading fast with no odometer function. Was busted up inside. A rebuild from a speedo shop in Ft Lauderdale did the job. About $200.
