The notch the sweep slides into is 3/8 inch wide, the channel 39 9/16 in width. The hanging down part of sweep measures 9/16 or could be 1/2--hard to get a tape on it. What sweep do you recommend. Thank you.

Hello, again. It's hard to make out the shape of the original sweep. This might be something like our 40-209, but look it over and tell me what you think.
