We unfortunately don't have a smaller version of the 91-179. I also don't know who may still have this. Storm windows in general have been dying off for decades now and replacement parts are getting harder and harder to get a hold of. That's just the reality of the industry right now, unfortunately. What you have here may be a collector's item. Your best bet may be to cut the 91-179 to size, but even that's not a guarantee. Just note that any products altered in that way cannot be returned for a refund. |
