Thanks for posting. I am afraid we don't have an exact match for this bubble seal. Our 58-135 is the closest that comes to mind, with a bulb diameter of 11/32"--but I am not sure if this is large enough, and even then the T-Base looks potentially too big. Please compare and let me know if you'd be willing to give this a shot.
