Thanks Bill, that will help!
What kind off sealing sits between the windshield and the dash? I could not find anything that fills the hole.
I don't understand the question about a seal at the 'windshield and the dash'.
The windshield is completely sealed to the body via the seal around the W.S. frame. The can be no other seal because the frame has to remain movable.
If you are referring to the gap between the dash and the frame adjacent to the window operator, that gap has to be there to accommodate the crank out assembly.
I forgot to mention in my write up yesterday that you will have to remove the windshield frame from the car in order to replace the seal.
Removal of the windshield will require the removal of the sun visors and header panel. Remove the operator crank-out bracket from the bottom of the frame, two screws that will require cranking the windshield out to get clearance for the screw driver, don't force the screws, 'patience' is your best ally. If you strip the head and/or break the screw, you are in deep trouble.
The frame is attached to the two upper hinges, one each left and right. Some frames have screws attaching the frame to the hinge, don't attempt to remove these screws, remove the screws holding the bracket to the hinge, usually round head, slotted, with star washers.
Once the windshield is removed from the car you will have ample access to remove the old seal and clean the channel.
The screws that hold the dash in will also be more accessible, especially if you have to "worry" the screws out.
If your car has been restored at some point in the past the removal of the windshield might not be to hard, however, if the windshield has not been out of the car in many years the job can be quite difficult.
I had to get a replacement frame for my '36 Ford truck, the frame was very badly rusted away, which is typical. I found a very good one in Atlanta Georgia. Pretty spendy, but very nice. I worried the screws out using a heat gun, BLASTER and patience. Had new glass installed, which was no problem because I had taken the frame apart. I repainted to satin black on the back side, installed a new rubber seal and put the windshield in the truck..
Foot Note! I don't recommend using glue/sealant on the windshield seal because if the channel is clean and newly painted the seal will lock into the channel and will not allow water to accumulate in the frame.
There are two holes in the lower corners of the windshield body recess. These are drain holes that direct water out of the area into the front quarter panel cavity via two small hoses... Good time to clear the holes of debris and put new hoses on same, while the dash is out fixing the window operator.
