o,
Before you get the D tool, why not get a set of the knurled screws and just have them replaced. They then can be adjusted with your fingers. You just need to find someone to take them out first, maybe the local shop? Anyway, not a big difference in price, but they do make things tons easier. I didn't think they would matter but I find myself adjusting as the year goes by for temps. A quarter turn makes a noticable difference when it gets really hot and humid out.
