Seal for Door Threshold with a "T" type track

Question

I cannot find any source for this type of Threshold Seal here in San Antonio, TX.

The Threshold is not removable as it is secured to the door frame.

Can you please help?

See our 58-134 or 58-135. Take a look, compare the end profile dimensions, and see if you think one of these T-Slot Bubble Seals might work for you.
