Does this alignment shop diagnosis sound right?

[csp97]

I just got my ’82 300TD back from the second alignment shop this week. The camber is off visually and the front tires are wearing on the insides. The first shop (small town guy) replaced the center link (loose) and put on some new tires before realizing he did not have the Mercedes tool to do the alignment. So I search on the forum and realize it’s not a straightforward job to align these cars.

Most people seem to recommend the dealer for an alignment. Well that’s nice, but I’m in the TX panhandle, about 3.5 hours from the nearest dealer in Lubbock. I call some foreign car mechanics in Amarillo and get an alignment shop recommended to me and take the car to these guys. They don’t have the Mercedes tools but claim they can put some weight on the suspension and do a decent job (?). They’re cheap enough that I’m willing to give it a try, like I said the dealer is really not an option.

The guy looks it over and says the all the camber adjustment has been taken out. They do some measurements, and the front springs will need to be replaced before they can fix the alignment. The mechanic did seem at least a little knowledgeable about the W123 like he had seen this before. Does this sound like a decent diagnosis? Weak springs resulting in negative camber that can’t be corrected. He said the rest of the front suspension seemed tight.
