Joann - I purchased the window retainer strip and the sealant bead from
Airstreamdreams.com. I just finished replacing all of the glass in my 62 Overlander
( it was easier to replace it than to clean it ). The previous owner had
smeared a silicon all around them, what a mess and what a job to clean up. The
window retainer bead ( strip around the outside of the window) is made to match
the original and you would not beilieve how much better the trailer looked with
having just that done. Good luck.
