Thank you for posting. I don't believe aluminum glazing is still available. Most manufacturers have replaced it with the vinyl type because of the cost of production. We do offer many varieties of vinyl glazing and would be happy to help you find a substitute. How do the dimensions of the 55-006-6 match your sample?
