the fixed triangular window seals are the only ones that has lasted over 30 years.
Look at all the seals on a mk1, and try to find one for the triangular FIXED WINDOW, that have been weathered...
That being said, "smokers windows" AKA vented triangular windows, is totally different story...
The only time these are destroyed, is probably similar to the case you have; someone butchering them out.
Look out in the classifieds, and even post a WTB.
It took a while for me to get a set, but all things come to those who wait.
If they're butchered up, just leave them in until you find a set.
