Romm,
If the center post was tightened too tight, this definitely could cause the windshiled to crack...
A lot of people tightened those posts to keep their rear view mirrors from "wiggling" when they drove and didn't hink about the extra stress' that they were imparting on the glass...
Don't get me wrong, you "could" have defective glass...
Call SPF USA and talk to Barry Bloch about it...
Luckily, with your car #, all you would "need" to get would be JUST the glass itself.. But DEFINITELY check the frame for undue tensions/stresses before installing the new "glass"... Otherwise.... Well, you know...
