I have quite a number of MB tools considering that I am not a pro tech. The only ones that I have that I think could not be substituted for in some way, are my head bolt sockets. That said, a friend of mine, bought a set of Lisle sockets that would cover these two items.

I have:

Drip tube
Timing rail pin puller
Injector Socket
Head bolt sockets
123 Valve Adjustment Wrench set

Good luck,
