73-87 WINDSHEILD SEAL - DELUXE, Cheap or expensive? does it matter

[NASTY-LSX]

I was on BROTHERS TRUCKS website and called for a order. For front and rear
windsheild with chrome trim was $126 bucks. I told him to hold off and would call back. I called local glass shops and they want $18 bucks a piece.

Do the seals come from one place?? would there be a difference from
cheap and expensive seals?? If I have to pay the $$$$$$ for good seals
I will, But if I dont have to, I wont.

Where do you buy from?? or best place??
