300 SD Torque Converter Bolt Part #

Started by amilio, 03 January 2024, 11:23 AM


Hi all, doing a transmission job and saw that the hex bolt on my torque converter is in poor shape. Wanted to replace it so the next job doesn't start with a stripped head. Does anyone know if this part would fit, and if not, what the right part/part number would be?

The part number is 124-990-21-01.  They show to still be available from Mercedes for around $23 each. Rather pricey for a bolt even if it is a grade 10 or higher bolt.
