Hot Rods 1933 Extended cab build : Pt 1 - windshield removal ?

Looking for some guidance here ! I am disassembling a 32 cab for a multitude of
reasons - structural damage from a minor accident, rust repair at the bottoms,
eventual windshield replacement etc. The 2 most outer windshield mounting screws
are not accessible by any means from where the roof is covering the area at the top
of the A' pillar. Removing the roof panel - everything around the perimeter at the
rear panel / roof is out, and the B' pillar rivets are removed, the 3 bolts at the top
of the A' pillar are removed but the roof is still attached. I have attached a picture showing
some "extra" welding that was done at some point in its lifetime - that has been opened
up but it's still attached. There appears to be at least 3 factory spot welds directly
above the bubblegum welding ( as shown in the 3 circled areas ) so if I break these
loose from the upper portion of the cowl, will the roof section become separated from
the cowls header panel or are there more welded areas I should be looking for ?

 

aren't there just screws that go up into the header on the inside of the hinge?

 

Yes, there are - all of them have rusted, some are / were stripped, and the 2 outermost
screws are inaccessible with a screwdriver, unless there is some sort of angled version
or a universal joint before the tip

 

Been awhile since I removed one of those, but I'm sure I didn't have to remove the roof to do it. How about just cutting the heads off those 2 screws with a chisel or die grinder?
Also, they make 90 degree screwdrivers, some even ratchet........not sure what would work without pics?

 

Will be following this as I'm certain other owners will as well, I believe at least two roof versions were offered in the 32-34 cabs, a welded & leaded seam & an open unfilled butt joint, however unlikely either required removal to service a glass replacement, & yes, I do see where roof removal may be of benefit to your case in point & anxiously await replies.

 

I just removed the windshield from my '34 last week. I could get to all the screws with the window propped open with a piece of wood.

 

That's exactly the way I removed my windshield frame on my '32. HRP

 

are the inner post garnish molding off?
do you have a photo?, I have never had to remove a roof to change a windshield on ANYTHING
