Shower Door Sweep

Hi - I need to replace a shower door sweep that slides into the bottom of a hinged shower door. It is a T top - the top of the T measures 1/4 inch across. It is 36 inched wide and 1 inch deep. Can you please help? Thanks

Do you have a product like 10-321 but with a 1/4 inch t top?
I am concerned that the 10-321 would fall out because the T top is 1/16 inch smaller than the one I need to replace.

Thanks
Stan

Tom - Thanks for your reply. Since I need 36 inch sweep in brass, and 10-326 does not come in brass, I was thinking trying 10-313 and cutting off the top T and use the second wider T to slide into the channel. Do you think this would work or is the second T too thick to slide into the accepting channel? Also, my shower unit is a Muskee made in Ohio. When I called them, they said their doors were made by Coastal. When I called Coastal they said try ebay / internet. I have bought parts from you before and you were my 1st stop on the internet. What do you think about modifying 10-313 or do you think I could get 10-326 in brass somewhere else if you don't have it? Thanks Stan
