I have been checking the part numbers.
W113042 PN A 001 545 55 24 (there is no RHD or LHD, one number) used only on W113
W113043 PN A 001 545 55 24 (no RHD or LHD) same part, until chassis 0 02979 used only on W113
Then as of 043 002980
W113043 PN A 002 545 29 24 LHD used only on W113
W113043 PN A 002 545 54 24 RHD used only on W113
Then
W113044 PN A 002 545 29 24 no LHD and RHD, one part number
No match with any W108 or anything else
