Manual transmission specs for 240D?
 

I am replacing the clutch in my 1980 240D (early transmission) and I am continually frustrated trying to find torque specs. I did finally find the specs for the pressure plate screws, but now I can't find any specs for the bolts/screws holding the bellhousing to the engine. I suppose I will just guess at these, but I hate doing things half-assed and I can't find any indication that MB ever published word one about the transmission. I have the engine manual and both chassis manuals. I have the MB manual set on CD's, too, but nothing I have even mentions the existence of a transmission (or the rest of the drivetrain, for that matter.) Very frustrating. Does anyone know if there is any way to get a manual for the drivetrain for this car? Even just a sheet of torque specs would be great. I have searched the web and this forum for weeks and come up with nothing, though it may just be that I haven't found the right words to search on. Thanks for any help.

No real spec, but rule of thumb for a 8.8 grade 10MM bolt is 25-30 ft lbs.
