Is anyone familiar with a seal or cushion that seals the air space between the rear window of the cab and the sliding window of the topper?

Is there a name for this item, and who might sell this?

Appreciate any feedback.

 

I've seen them on ebay, just search cap seal or topper seal. I can't remember what I searched but it won't be hard to find.

 

Search for boot or compression boot

 

They make different types, I had this type many moons ago it seals the cab to the shell but you have to remove the windows on both the truck and shell, works great.

The other type is an inflatable boot that leaves the windows in place. But tends to rub the paint off the cab after a few years.

Thank you all, good people for your prompt and detailed replies to my inquiry about the seal between the cab and the topper. All the Best!
