Sealing between bed cap and cab

[Ranger97XL]

I was wondering if anyone has a bed cap that is sealed to their cab?

like the truck in this thread:

I'm not really concerned with paint rubbing off, my truck isn't exactly beautiful. Neither my truck or my top have a sliding window, so I am looking for something permanent, I want to have it open to the back for during the summer to have the windows open, and so my dogs can stick their heads in the cab to check up on me while driving

I did at one time, just check with a place that sells toppers.
