WTB one front stabilizer bar bracket,1153200845. (holds the bushing in place) It is for a 1988 560sl, but is the same for most SL,and same as some 70's vintage 220d,240d,and 300d.

Is that the one under the battery tray? I've got a couple parts car's.

the battery on a 560SL is in the trunk, not sure about the others, but it is a bracket for the front sway bar(or stabilizer bar). There is one on each side but both are the same.
