Oh about the engine carrier(hanger), since front sub frame is almost the same between W114 and early R107 with M103 ,
you can just use ones from R107 with M103(6 cylinder ohc).
part numbers are
A 103 223 01 04(right)
A 103 223 00 04(left)
they should be bolt on.
I've got A 103 223 00 04(left) new and fitted to my M104.
But the problem is Mercedes don't have stock or make A 103 223 01 04(right)
anymore.
Voisiko joku asiasta tietävä vahvistaa (tai kumota) tiedon.
