The 36s need a little work but one of them is missing its valve cap and the other one is cracked from age, so I am seeking two replacements. Your post about finding the cap from a tube of Costco Kirkland brand hydrogen cortizone. intrigued me. Was it a good fit. Could you offer any more details on that or did you eventually find the part? I am struggling to find one anywhere. Thanks Alan!
