I have a '67 Overlander with window frames that are in relatively good shape (including hardware) but the window panes are broken and in need of replacements.
The screws that are in the part of the frame that holds the glass panes in place are totally corroded, so upon the advice of several more experienced folks, I started to drill them out. I ended up dissolving the screws with a drill, basically, and I wasn't able to actually extract the screws of the first frame I started on. I'm including a photo of what the screw hole looks like after I attempted to drill out the screw. I seem to be hitting a block of some sort, maybe the aluminum frame? I am not able to drill all the way through the frame ( and probably don't want to), but I'm not really sure what I'm hitting.
Any help or advice is much appreciated. Thank you!
Here is a link to the photo of the screw in my frames.
