Need help with sliding roof W126

[MS Fowler]

I am trying to reinstall the sliding roof on my 1982 300SD. I have lost the notes I made upon disassembly. I need to know a few things;
1) How are the front and rear seals installed and retained. Real clear illustrations appreciated.
2) How to reinstall and connect the roof panel. A few Specifics:
a) Where does the little half circle with a flat bottom flange on the tube rest and how the spring clip fits it all together. This is all at the rear of the "bridge", I think.
b) I ahve a pair of small discs ( rollers). Do they run up on the piece that depresses the deflector?
c) I belive the stainless steel spring clip ( the one with what looks like fingers) installs at the front of the sliding roof panel. Is that right?

I made pretty extensive notes when I took this apart ( almost a year ago) for repainting the entire car. However, that entire notebook has become AWOL, and I need some help.
Thanks.
