RV Repair: Replacing the canvas sides, tent trailer, jayco

Question
I was recently giving a 1983 Jayco j series 803 tent trailer. The guy that gave it to me started to replace the canvas sides. He removed all the sides and hardware. He gave me the new sides and hardware, but no instruction. I searched the Internet and all I could find was  do the opposite as when you removed the old one. No help here. Any tips or suggestions would be greatly appreciated. Thank you.

Answer
sometimes they are hook and loop, sometimes they are screwed in.  Newer ones actually have a lip on the new canvas that fits into the channel that is at the top of your ceiling.  It just presses into the channel much the same you outside door does when you set it up.  

If you want to see one in place, go to a camper store and pretend to be interested in shopping for a new pop up.  Then look at how that canvas is attached at the top and bottom.  Amazingly simple.
