OK--here's my take. Vinyl and adhesives do have a shelf life. it is POSSIBLE that there could be problems related the aging of the stripes while they were stored. On the other hand they may perform fine.

I do not know of reproduction problems related to original appearance/cut/color etc that would make them poor choices for a resto but maybe thats the case with some stripes.

Strikes me as taking a gamble for little/no benefit.

Just my opinion.
