Where is this code? I have 5 diff's sitting in the shed and I sure would
like to know if any are 4.1...

Geo, thanks for the suggestions but the real problem I am trying to beat
(with a list of cross references) is when I am talking to someone on the
phone and we are trying to identify what the diff ratio is. You can rely on
most folks to read the code off the case, but not to calculate the ratios as
per your suggestions. And most folks are reluctant to open up the case. I am
sure there is a list somewhere and it would be handy for tracking down a
diff with a particular ratio.
