I removed the dash on a 1985 W123, to check the climate control system, but can't get it back in. I read some detailed post about removing it, with a very brief explanation of how to reinsert it, but it didn't really explain how difficult a job installing it is. I just kind of was hoping someone had a technique that worked for them. Otherwise, this is a warning to not remove the dash unless you don't plan on putting it back in. This is a very hard thing to do. I tried for an hour to get it in without breaking it, then I spent an hour trying to get it in with no care to damaging it, and still couldn't get do it.
