Well, funny you mention this now. I thought about the same thing recently, for good reason - and I will be selling a complete OEM Webasto manual sunroof assembly for the W111 series cars next week. Originally, I thought about keeping it for an install on my W108, but decided against it due to the curvature of the W111 roof. The sunroof master panel would fit reasonably well, but the mounting angles of the frame members of the sunroof would need to stay the same, so the roof assembly would need to be adjusted with spacers to the roof rails of the W108, assuming they line up decently - if not, simple aluminum brackets would need to be made. The other issue is that dropping the frame elements of the Webasto roof down a bit with the spacer will necessitate some careful modification to the headliner - not the end of the world either, really. Ultimately, my reason for deciding against the project was simple - I will be installing the rollback canvas roof from a Ponton instead, as I favor the size and style more. I think the Webasto is a really solid option, though, and if you are willing to invest the time and work I think it would be a stunning mod. You will need to bevel the roof opening once it is properly cut, and treat the area for rust prevention very thoroughly.
The nice thing about the Webasto roof is that it was engineered by Webasto specifically for MB, and as such it does not need to be "cut out" per se. The roof opening will need to be cut as I mentioned, but the entire assembly from Webasto is modular, and installs with common hand tools. My original German parts catalogue for the W111 lists each component of the Webasto assembly as a separate MB part, but I will be selling the entire "kit" so that someone such as yourself, or for an easier job a sunroof-less Heckflosse owner, can install the factory parts. My assembly includes ALL parts, from fasteners and drain lines to the frame, latch mechanism, rails, main panel, and fabric liner. The liner is not the best, but you would want to use the cut section of the W108 liner anyway to ensure a match. All you would need to do would be to cut the hole for the roof, make the brackets from simple aluminum strips, and drill holes for the mounting bolts to attach to the roof rails of the W108. About $40 in common hardware store items. If you are good with body work, not a very bad DIY, and thus also not a terribly expensive job for a shop. You'll want to repaint the roof, of course.
Drop me a line at my website if you are interested or want to make an offer, otherwise it will be hitting eBay next week. Modern Restoration and Design
Of course, the BEST option would be to find a sunroof from a W108. Maybe a W126, failing that.
