Hey I want to replace the back window weather strip on the 81. What does this in tell? From he look of it do I just rip out clean and glue it back? Seems to simple.

It is too simple!  Just pull it off.  The hardest part is getting the old adhesive off.  I have seen some with one or two small screws holding it on, so look carefully first.  Then use good quality adhesive, and tape it in place overnight.
