All the Blazers are rusted out, even down here in the south!
Broncoscare if you've been to Jeff's, then look on page 82 of their catalog, there's a pic of the top, and seal there. the ******* goes on the truck, the soft one goes on the cap, the "big corners" fit into the rear of the cap.
There should be no adheasive on any of the seals, but they may get stuck with age, and tear when you remove your top for the FIRST time. That is why some folks recommend buying a new seal set before your FIRST removal.
Go with what ktomek said, and you will be ok.
