Roof lip/above windshield patch panel

[SoNorth]

So first off, new to the site. Looks like there is tons of great info on here.

I've done a bunch of searches and looked all over the place to see if anybody makes a patch panel for above the windshield for a 64-66 cab. I know they are available for 60-63, but I haven't really found an answer as to if that panel is the same on both style cabs. I actually need the inner part too, but that doesn't look as hard to fix as the outside. I know they make inner panels for the 67-72 style cabs, but not sure if that will work for my cab with a little modification?

Any input on this would be greatly appreciated. I know there is always the option of cutting the roof off a donor cab, but clean cabs aren't that plentiful in the midwest.

I have a hard time believing nobody makes these panels since it seems like a very common problem area.
