t-slot offset foam seal

Question

Will the product code 58-182 and 58-183 fit and seal the same window. If so, which seal is considered the best to use. My original windows appear to have the 58-182.

The "T" slot size is the same for these two products, but the 58-183 has an extended shelf extension, allowing the bubble to go further under the sash. Please compare that detail to your old seal.
