I have a 1979 350 SL roadster M.B. (grey line)

Where is the fuse relay box; can't seem to find it?

Also, my experience has been in the past that when I ask a M.B. dealership if they'll order parts for me for my greyline car, no one wants to do it. Does the PartShop order grey line parts and would they even want to? I know it's a hassle.

What should my idle be set at? thanx
U guys are great!
