Re: Rear wing window removal

It is a bit involved. There are some instructions in the body section of 46-50 service manual which starts on page 6 with directions for removing the glass. Some of the screws mentioned in that portion need to loosen when removing the vent and then front wing removal directions starts on page 9. The photos are of a 48 but 46-7 cars come out the same way. Basically it is the same procedure for front and rear with just a couple of differences.

IMO, fronts are relatively easy compared to rears. On fronts you can see and get to the nut on the bottom pivot shaft. Once all the weatherstrip retainer screws are removed and the bottom screws on the side runner channels are loose you can tilt the window frame assy away from door frame just enough to get at the top vent pivot retainer screws to remove the wing pivot retainer. Once that retainer is out and bottom nut is off you can pull the vent out of the rubber at the top and then pull the bottom shaft up thru the weatherstrip and remove the vent. When the vent bottom nut and washer is removed the spring will be loose and come off. There is a stop piece with a square hole on the shaft which may need to be gently persuaded off the shaft as the vent raises. Watch the assy order and how the stop piece is oriented so you can replace it without experimenting. If the rubber is hard and brittle then it is a different story. Rubber has to flex some so if it has hardened a lip may crack or a chunk break off.

On the rears SM doesn't go into much detail but the pivots are slightly different and in a different spot. Access to the lower nut is blocked. You have to completely loosen the window channels, disconnect glass from regulator, and then tilt and lift the entire window frame assy out away from door frame and up enough to reach the bottom nut. Block the assy with something while you work on removing the nut. The top pivot is a special screw which threads into the top of weatherstrip retainer and extends down into the vent frame. It is just the screw and not a removable retainer piece like the front vent uses.
