Sixto, there are two eccentric bolts, one in the tie link to adjust toe-in and one in the pulling link to adjust toe angle. This is according to the 1984 "Introduction into service" manual for the W201 (190E, etc.), where this 5-link suspension was first used. The W124 has an almost identical rear suspension. When I had my '87 aligned, I had to take it to a place that could do a 4-wheel alignment.

Army, the differential is smack in the center, near as I can tell without a measuring tape.
