I see the 14 mm hex socket is common on the differential and the transmission drains and I got one of these.
I'm wondering what other sizes of the hex (allen-type) sockets should I obtain to be ready to work on the Mercedes - mostly w124, w123, and w126 models ?
I ask as I have an assortment of hex sockets that I'm selling on ebay in the next few weeks and want to make sure I keep any that I may need in the future.
