Norco weatherstrip

I am looking for replacement weatherstripping for 1983 Norco casement windows. There are two kinds of seals on each window. One is a white silicon 1/4" bulb seal with a flap on one side which goes around the frame. The other one is a leaf seal that is brown (color doesn't matter) and appears to be made from PVC and has a deformed bubble due to the crush between sash and frame. These are replacement seals Norco sent back in 2004. The original leaf seals did not have the bubble, they were more like your product 55-170.
