I have some from my convertible. I took them while I was waiting on the black weatherstrip glue to arrive, and I never took pic's of the glued ends. it'll take a bit since I'm not home and at a friends house wrenching on his car right now. I should have them up tonight by 4 ish.
as for gluing the top end by the windshield it should look like a sideways 8 (glued in the center to let air out. that way when you glue iin the piece at the quarter seal groove you can make it closed (plus it stops the tubing from peeling away from the pinchweld.
this is the way I do the windlace seal.
here is where it ends at the windshield pillar on the convertible. the hard tops will go right into the top side window seal , we sealed them with black butyl like glue at the factory in 68-73 when I was there (thanks fully I got transferred to a different plant and didn't have to work in that environment anymore). tubing is longer than the pinchweld part on the top also for hardtops just like the quarter seal in picture #3

then it gets pushed on and sized in the corners so that it fit's tight to the curve and doesn't pull out when you got to the floor part(I use a small plastic headed mallet and a rag to get it onto the curve tight)

passengers side quarter window seal and windlace push on part trimmed so the tube is slightly longer and fit's into the quarter seal. you can see where it wants to separate from the pinchweld seal. that gets glued back on to the pinchweld after you seal the end. (I use a dab of super glue to stiffen up that area, but the black weather strip adhesive works too!)

here's the drivers side in the seal and waiting to be glued into place.

hope this helps.
Remember there's always other ways to do it that work also. this is just the way I do mine.
