Measuring thread ODs is full of pitfalls because you never know how much the thread crests have been rounded off. Look up the "3-wire" thread measuring technique; I think it's covered in the handbook. I've never done it, but it looks like an accurate, but difficult, way to remove the uncertainty. I agree that this inch thread in our cars is pretty hard to swallow. ;-) - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Too much?
