Hiya Supertax and thanks for the thread,didn't know it would keep ya so busy. Nice Tok36 used his toys as guinea pigs and you found a solution. I'd recently sold a 97b and I understand its undergoing CZC treatment to have it become ambi safety, with them needing to use 75b's set up. The conversion priced at 300 bucks,so its possible but not inexpensive. Be well.
