This is interesting....
My 68 vert Non A/C has a Flapper valve to seal the rear vent from returning air and water. No cable or vacuum actuation. I never saw any "filter" material when I had it apart. The flapper is on the cabin side of the assembly. There is also a hard rubber deflector in the rear deck vent to guide the rainwater to the drain holes.

I think my '70 vert is more like this set up. Fronts controlled by levers on console. Rears are manually actuated on the rear aft deck by a hand lever/bail mechanism that moves about 90 degrees. I've never looked it up in the books to see what is says.

Yes, but is that the front kick panel vents which are cable operated? we are talking about the rear vent and the door in the rear of the cabin. If your rear astro door is cable operated it seems it is another variation. BTW my 68 is late production as well.

Mine is April 26, 1968 and same setup...
