After 15 years the weatherstripping around the windows of my 94 z28 convertible have seen better days. I adjusted the windows as far up as they will go but I still have leaks around the top of the windows. I found a couple of places on the internet that sell the original weatherstripping but one place wants $86 each and another $124 each. Any ideas?

 

The weatherstripping themselves are mounted in rails. If you pull the rubber off (be careful, they're glued in too), you can adjust the rails on their mounting screw slots outward. That might help some too.

Here's a pic of the mounting screw on one of the rails:
