Framed Shower Door "T" Top Sweep

These are photos of a scrap I saved last time I was able to locate what I needed at Home depot who no longer carries it. No luck at Lowe's either. "T" top is 3/16" across, and 5/8" from top of "T" to bottom of strip. Clear silicone. Tried a generic double t top that was longer as well and it ripped right out of the drip rail first time it was closed. Too long, binding. Would like an exact replacement.
