I wasn't trying to rain on your parade OVRTRQD.
I was just relating my personal experiences,I'm sure they're not all bad.
Like Alvin said,your 'original' glass might not all be as it was when it left the factory.
A lot can happen over nearly 60 years!
Check your new glass against what came out your truck and it'll give you a better idea of what you've got to work with.
Good luck and as Alvin already mentioned,let us know how things go.
