[Healeys] BN7 Windshield

[David Schweninger]

  I have started to assemble my windshield and upon unwrapping and  
cleaning up my old glass I found there was a yellow stain about a 1/2'  
all around the edges.
This looks like it was caused by the old seal and apparently is on the  
plastic between the glass.
  If I slide the glass toward the top the lower corners are inside the  
frame.
  Any ideas to get rid of the yellow, or recommendations on where to  
get a new wind shield?

  Thanks,
          Dave and Daisy
