Boatcover windshield channel plastic

[Rowdyroady]

my 2001 Chris Craft 328 uses a plastic channel sewn onto the boat cover to attach the cover to the windshield. Then snaps the rest of the way back. That plastic channel is cracking and drying out...needs to be replaced. Where can I find something like this? Looks to be pretty specific to this windshield.

Discontinued of course, but was fortunate to locate a roll of this stuff. Getting my canvas guy to sew it on next week.
