Thanks Toby8
i would have thought a welded in cassette sounds like the easiest option when I have t replace the whole roof from pilar to pillar including the frame and the hood lining etc anyway. My Panelbeater is a good craftsman.
Is it not just a matter of positioning the cassette in the right spot in the replacement 02 roof and re skin the actual sunroof panel with 02 shape? I know that sounds easier than it will be in practice but that is the basic mechanics of it yes?
If the fabrication to connect the e30 cassette to the 02 roof costs me around $1500 it will be only a small part of this full Restoration and a lot better than slotting some cheap aftermarket glass panel pop roof in there?
