Talk Morgan Forums Thread Like Summary - Windscreen angle adjustment 1970 4/4

I'm looking for advice regarding the removal and particularly the re-fitting of the windscreen and side pillars on my 1970 4/4. The problem is that someone in it's past has fitted the screen at the wrong angle - the picture should show the side screen rubber overlapping the pillar at the top. The windscreen needs to be mounted more upright i.e. more towards vertical. I have purchased new base rubber gaskets (don't ask how much!!!) but was wondering just how much adjustment (towards upright) I can make when refitting everything. Any advice is welcome - I will likely be doing this without a helping hand (i.e. just me) - is this possible?
Thanking you in anticipation of your advice.

Just a little point to note, if you move the 'screen more upright you may find it makes it impossible to fit the hood (which looks like everflex in your photo)

It may even be a previous owners tweak (bodge) to compensate for hood material shrinkage
