I’ll be there when the glass is removed by the fitter. I will advise about these little blocks. Are these blocks featured in all second generation cars? Mine is an ‘81 and I’m unsure if the glass has been replaced in its life, the condition is pretty good considering it’s age.IF you've never done it before, it might be good to find an automotive glass shop to do the job. Watch how they do it and learn from that. Letting them do it also means that if the glass gets cracked, it's theirs, not yours to pay for. Plus a guarantee on the labor against future leaks.
In any event, you might plan on a new glass anyway rather than an old one, letting them get the glass and install it as a package deal.
It might also be that some of the orig sealer has aged and is in the process of releasing from the glass, which makes it easier to get out. IF you might see some little "blocks" of rubber at the bottom of the glass, those are there for positioning purposes when the orig glass was installed. Re-use them if possible. A good glass installer can see where things need to be, visually, and place the glass as it needs to be, first time. Getting it centered in the "hole". Once there, the glass stays put, if quality OEM-level sealer is used.
