I'm lucky enough to have two 300SDL's here at the house for me to look at for reference for when I put the rest of this stuff back together this weekend. I think I've found just about all the parts for it by now- considering i've done 4 or 5 other engines in the garage since I did this one, thats quite an accomplishment...
Now if I could only find Brian Carltons EGR plate kits I bought awhile back I wont have to buy a new gasket for the egr valve
