Norco Casement Weather Strip/Seal

A home owner from Michigan says:
Our home is full of 25+ year old Norco casement windows. Most have fogged up so I'm working on replacing the IGUs. On the exterior of the window is a seal/strip that I'm looking for a replacement for as most of mine or dry and brittle so they crack trying to remove them. These strips slide/lock in parallel with the glass, into the wood sash. Is there a replacement product I can purchase? Any advice of the best way to remove my old ones to minimize breaking? Thanks for your time.

Sure, this looks a lot like our 55-186. Carefully compare it to your own hardware and see what you think. As for removing the old glazing, see our video below on some tips.
