Thanks for posting. I believe either our 58-053 or 58-114 are indeed the best matches for this seal. A hollow versus foam seal isn't that big a difference--we've found there's no tangible difference in performance. What matters most is the dimensions that most closely align with your old seal. Please compare. Profile drawing of the 58-053 bubble seal.
