Anyone know of a brand or if it is a custom install to remove out the back windshield and put on a camper shell so it is a 'Walk thru' shell??

I had a buddy in high school who had a lower rider truck w/ a camper shell and it had weather stripping between the campershell and rear winshield of the truck. He said it is a "walk thru". I would really like to do this to my truck with a bedrug in place, but I wanted to know if they sell a shell that does this with weather stripping to seal between the shell and the rear windshield. Please advise if anyone has done this themselves and how difficult it was.

Thanks!!!

 

My first concern would be sealing it, because the bed moves a little bit on its own compared to the cab.

Sounds like a custom job.
