[Mgs] Replacing MGB windscreen glass

[Ed Woods]

List,

I am still struggling with what started out to be a "simple" windscreen
glass replacement that has turned into a struggle to remove the screws which
retain the four corner brackets. Very few came out in the standard "left
loose" manner. The remainder had to have their heads drilled out. And, yes, I
soaked them for days in "Blaster" and used heat before resorting to the
drill.

Any ideas about how to remove the remains of these screws? How much heat
will they take before the aluminum of the frame is damaged?

Thanks,

Ed Woods
