Bengt,
I have a glass that fits in the rear window of a phaeton or roadster. I don't know if it is an original or not. I mic'ed it out at .115". That is less than 1/8" - pretty thin. Looking at page 250 of the Ford Service Bulletins, it specifies the glass at .080" to .187" thick - a pretty wide range. 1875" is 3/16", so you are at the top limit. If your glass is 3/16" thick, that is over 50% heavier than the glass I have. I don't know if that is part of your problem or not. It is hard to replace glass in the top. What you could do is leave the top up (what I plan to do with my phaeton) or possibly make a "spacer" to sit in the top test bracket on the studs to lift the top a little higher. I am not at the point of installing the top on my 29 phaeton, so I don't know if I will have the same problem as you. Long ago, Dave Lopes told me, he never put the top down on his 28 phaeton and I like I mention above, I plan to do the same. He said the top would develop creases as the top was raised and lowered. One last thing - is the back panel with the glass in it, taught or a little floppy? I believe it should be quite taught. Good luck with your top problem. Maybe someone else has encountered this problem and will post their experience.
