Title: '41 Glass shape
Post by: Peter Cornwell on July 06, 2020, 11:16:29 AM
I'm pretty sure the door windows on my '41 convertible coupe have replacement glass in them as there are no date markings on it and the shape of it does not 'fit' the roof line (see picture). On the drivers side there is a gap between the top of the chrome trim and the rubber seal. Before I set off down the line of getting new glass cut to the correct shape, am I missing something else which would cause this to happen? The convertible top frame does seem to fit ok.
Kind Regards

I would check the window adjustment first.  It should be possible to bring up the rear of that glass for a better fit by adjusting the mechanism behind the door panel --- the door panel will have to come off anyway if indeed the glass needs to be replaced.

It's been awhile so I don't remember for sure but there should be some adjustment. I notice a floor shift, is that a '37 transmission? Is it hooked to a 346 flathead?    Harry

Harry,
Well spotted but it's not got the original engine or transmission (mea culpa), was like this when it was shipped from the US to England. It's a 4 speed auto box but the shift lever looks like a manual shifter.

Peter, No problem it's a beautiful car. I imagined an old school flathead with period speed equipment turning a '37 trans.  Sorry I can't remember about the window adjustment but if you take the door panel off as suggested you will be able to tell easily. Good Luck,    Harry

On the 40-41 convertibles there are adjustable stops at the top of the door that stop the glass at the appropriate place.  In addition the rubber seal mounted on the top frame can be spaced down with pieces of cardboard.  this was factory because on my 40 the cardboard spacers was not the same from side to side.  You can't know for sure that your glass is correct but the height of the glass was not a variable.  All glass was the same.  I don't remember for sure but I think the chrome frame around the glass also fixes the height of the glass.  The stops and the cardboard spacers accounted for all the variations.

Hey Peter
It looks like the window is all the way up on the front by the wind wing. If you adjust it up then the lower track may show.  Also if you push it up too
Much the window angle with incline towards the rear and look awkward.
You try what was mentioned to see if the rubber can be moved slightly down some. 

I have the same issue in mine but a much bigger gap.  I have read on the site here that there may be a way to adjust down the top mechanism that difference.  But it involves a taking a look behind at the rear side interior panels and then some adjustment work in the mechanism.  And it sounds like a mess to do.

I would Just drive with the window cracked down a few inches when the top is up and no worries when the top is down.

It's a puzzle, I like the thought of the cardboard behind the rubber. My concern is that if I use the rear jacking screw to lift the window, its going to open a gap at the lower left point (as viewed) by almost the same amount. It currently runs cleanly against the window track in there so don't think my answer lies there.
Have attached a picture from last week in our glorious countryside when I didn't need to be concerned about the side window fit.
