2003 SL 500 (R230) Engine Oil Dipstick Part Number

[jgl1]

Would like to acquire an engine oil dipstick for a 2003 SL 500, which did not come factory-equipped with such.

The vehicle does have an oil dipstick guide tube (# 112 010 17 66) but no dipstick, as M-B had phased out engine oil dipsticks at this point. Not looking for the dipstick oil tool but an actual dipstick that can be left in the engine. Can anyone direct me to a guide for oil dipstick part numbers? EPC for this vehicle shows only a cap for the guide tube and no dipstick.

The vehicle is 230.475, with a 113.963 motor and I suspect the proper dipstick would also fit a TYP 209 and 211 with the same engine.
