As I continue making progress on putting back together the back end of my white '71 TA, I need to make a decision regarding which stripe decals to use. I have NOS stripes I bought probably better than 25 years ago. They've been in good dry storage ever since. I also have a set of repros a friend gave me after finishing his TA project. They're about 14-15 years old and were sourced from Ames (one package has a Phoenix Graphics mailing label).
Can I trust the old NOS decals? Is there a way to "test" them to see if they're still good?


(P.S., my preference would be to use as many NOS GM parts on this car as possible, but.....)
