64 Chevy Pickup

Got a 64 Chevy Pick up to do.
As Scotty would say "That means it is an old truck !"
Question being, at that time, were the windows clear glass ?
The windows on that one are all flat as well ?
It is a Fleetside, if that makes any difference.

I've done a 60's something pickup before, but it was a rebuilt show car, so it had new glass in it.

I remember it having the standard rubber seals right up to the edges of the BG(like new superdutys, PITA) and the sides were adhesived in like a windshield.

This one has no gaskets in the door windows, they rotted out, but it appears to be the original glass.
If it is clear glass, is there such a film as 25% since 25 is legal in texas.

Supreme 28, which meters 28 on clear glass

Just be careful when tinting the original glass. Older glass can be a bit fussy, scratch easier when cleaning. On my cars, the glass is less stable than newer glass. Inspect it well.
