Rusted W123 trailing arm

[biobenz617]

Hi everyone,

I recently found out that my right trailing arm on my 300D has a hole in it and is getting worse. The shop quoted me at $950 for parts+labor including a used control arm off a junk car. That is probably not too bad considering what a PITA it is going to be to do it in my spare time, but I'm thinking of doing the job myself after I found a 280CE in the junkyard. Are the 123 coupe and wagon trailing arms the exact same part as the sedan?

Thanks!
