i know what you mean- the point at which the frame is glued to the
glass is coming apart- along with the coating on the underside, correct?
there are companies that can rebuild your existing tops- any of the
major catalog companies do- ecklers, corvette america, mid america,
etc, but you might want to give a specialist a call, like melrose t-tops

theres more out there, but i do not know of anyone else
if your glass is intact and not cracked or anything, it should be repairable. it may not be as bad as you think
