Windshield and Backglass Chrome Locking strips Question

[78 Chevyrado]

So both my Chrome Locking strips on both windshield and back glass have yellowed like they all do.  The rubber Gasket was installed around 2008 or so.  Do you think it would be a problem for me to put a new lock strip in that old of a window gasket?  I want them to look new again but I don't want to cause leaks or tears in the old gasket by installing them. If I need to put in a new gasket I'll wait a good while longer to replace them...lol

I know the tool to install them can be a little rough on the seals being old and likely hardened.  Have any of you done this successfully on an 18 year old window gasket?

Can't believe it's been 18 years since I restored the truck and I was here on this site doing it!

That restore was a good write up.  18 years ago, wow...
