The problem, Dave, is that the grab iron holes are offset vertically, so your method won't work without knowing how much the vertical offset is, and then doing a little math. Hence the measuring method I described. A digital caliper, Mitutoyo or Starrett or something cheaper (Rex Supply has a cheapie Fowler on sale for 15 bucks) can give quick and easy measure of all sorts of the things we use in the hobby, and can be useful for laying-out, alignment, and so forth. Old eyes like mine don't do so well anymore reading the little marks on a dial or vernier caliper, and besides, a good quality dial caliper is almost as expensive and a good quality digital.

Mine has inside and outside measuring with somewhat wide points on the outside measuring jaws and sharp points on the inside measuring jaws. I guess it would be just as easy to stick a divider or compass in the holes then pull it out and measure the spacing with a mic. or dial? Just one more step. ......DaveBranum
