another vote for Jon as one the great blokes selling stuff on the interweb. i bought one of his his uncut kits a few years back and have replaced a few seals on my canon fd bodies as well as my rb67 with 2 120 backs. his instructions are very precise and I am not even half way through the foam. he was very responsive and posted the kit to australia in not time at all. if i didn't have so much of the original kit left over i would be doing business with him again.
