Truck Cap gap between Cap/Cab

I traded in my 07 TRD Sport on a 2016 TRD Sport and got a Leer Cap installed Monday. I didn't realize there would be a 2-3 inch gap between the cap and cab. Does anyone has a solution that will allow the cap/cab windows to be open while driving and keep the rain/water out?

I was hoping to allow the dog to visit with the kids while traveling.

 

Thanks. Nothing like that available where I am. I will order it online.

 

I think I got mine online.

 

What size did you buy to fit the tacoma?

 

$30 Trail FX 30000 Truk-Boot, 24"X16"

Just be sure it is the size you need.

 

I can check to be sure later. At work now.
Let me browse through some old order records to see if I can find it.

 

TRAIL FX 20000 Trail FX
is the one I got last year from Amazon.
20"x 13" boot.
I tried to put it in once and put it aside until I had more time to spend on it. So, I don't have it in there right now.
My dad used these all the time in his trucks.

 

I have an ARE v-series shell, btw. In case you were wondering.

 

Another thing that you may want to add prior to the boot is some 3M clearbra where the boot will touch the paint. That was what I needed more time to do to mine. I have a front flip down slider so I can do it easily (I hope).
Hope this all helps.
Good luck.
