When I repaired my totaled 93 400E and had to replace the roof,
I opted to do it with a German roof as it had no sunroof. Did this as in the South they are more pain than worth and it gives you more headroom without it. Also too cold in the winter, too hot in the summer and too windy to use on the interstates, so why drag around the extra weight?
Anyway, mine was not damaged and I have the whole unit for sale. If you want just the frame I removed, no problem. Hardest part was removing the headliner to get to everything, time consuming mainly.
Good luck with your repair,
