window in convertible

[Mark McDonald <tomswift@xxxxxxxxxxxxx>]

I was talking to a guy who does vinyl tops for cars, and we were
discussing the possibility of me getting a new top on my '68 Crown
convertible.  He told me the rear window would have to be replaced,
otherwise it would "delaminate."

Thinking he thought it was plastic, I explained to him that it was
glass.  (And it's in perfect condition.)  He said it didn't matter; it
would still have to be replaced because the way they made them the vinyl
is attached to the glass in such a way that when you remove the vinyl
you either damage something or it won't be strong enough-- I'm not quite
sure what his reason was, but the point is he would have to use new
glass.

I find this hard to believe.  First of all, glass is not a laminate,
like say, Formica.  Is it?  I have to wonder now.  So I don't see how it
can "delaminate" if it's not of laminated construction.  Second, it
appears to me that the glass simply sews into place.  Third, I have a
perfect rear window, and it's original.  I don't see the point in
chucking it out.

Anybody know the facts?

Thanks, Mark
