Shower door sweep gasket

A quick learner from Cherry hill says:
This gasket sweep slides into a t shaped channel but I cannot find the right size anywhere. The door is 24" and from the early 1980s. Advise? Thanks.

The closest match to this sweep we have I believe is our 10-313 , but I have doubts it is a match. Compare the end profile dimensions and see what you think. Our other recourse for you is to replace the drip rail and sweep entirely: see if our 10-324 , 10-325 or 10-326 could work for you.
