I just finished restoring mine. I took mine apart when I took the car apart for restoration. It was hanging from the ceiling for several years while I restored the car. I did everything on the car except engine rebuild (Metric), body rust repair and repainting, which was done by a nearby vintage body expert.
When the car was finished (mostly), and while Covid 19 had me locked in for the summer, I started the hardtop, which had already been rust repaired and painted along with the car body. Experts from this site along with the Technical Manual answered questions and provided advice as I encountered ignorance-related problems.
Everything related to the hardtop restoration is possible by a mechanically inclined person acting "alone", if you have a chainfall or another way to turn the top upside down or right side up when it's time. I did the work on a quilt-covered door laid on a shipping pallet supported by two saw-horses (I'm a cheapskate).
Gernold Nesius' write-up in the Technical Manual was invaluable during the process.
The only problem I had was reinstalling the rear window (not the quarter windows). I had an aftermarket rear window seal which was dimensionally incorrect (too long on the top segment, just right ont the bottom segment and too short on the two end segments). In the end, bought a MB-made seal for about 50% more than the aftermarket seal cost and installed the rear window in a matter of an hour or two, alone, including roping-in the seal and installing the chrome.
If you decide to do it yourself and have the confidence, time and patience, you can get lots of help here and probably save half (or more) of the cost of having it done.
