Not familiar with your exact problem but I think my 52 panel is about the same.
Question....did you pull the vent window glass out of its frame and put new tape in it?? If so, maybe you pushed the glass back into its frame to far???

I had a similar problem but I also did my vent glass....and when I put the vent glass back into the frame I closed the vent window and then "pulled back/out" on the vent glass a little to make it snug with the vertical seal without compromising the seal of the vent glass its self.
Note: I had tried a steele seal on another AD, before my panel, and was not impressed with it or the cost. I ordered the ones for the panel from Classic Parts and have never looked back and that was 5 years ago.....just saying!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
