Finally found a W124 in a local junk yard. Grabbed the sunroof lift arms out of it and finally go to taking my sun roof off. Sure enough one of mine was cracked which was causing it to get caught up. Wasn't nearly as bad as I thought it was going to be. Definitely learned some stuff on the junk yard car, and learned more stuff on my car. Messed up my headliner piece a bit, but not enough to notice unless you're looking for it. Could definitely to it again without messing anything up now.
