Steering column boss question
 

Hi All - Im new so hope this hasnt been asked before.
My Researches seem to indicate that all steering bosses to enable a new wheel to be fitted to mercs, seem to be the same part number regardless of the car in question.
However i have a merc 610d vario truck that i am converting to a motorhome, and can find no info on the steering column anywhere?.

Does anyone know if merc use the same column on all vehicles - and if not, how can i find out which boss will be appropriate for mine.

Hope u can help
Cheers

Dave
