Wheel Backspace measurement and NeOkla Region Thanks

["Robert & Katherine Seamon" <forestg@ionet.net>]

I just measured the backspace on my Ford Escort GT 15" wheels and it came
out to 120mm.(There was a circled 12 stamped on the inside of the wheel
which seems to back up the 12cm measurement.)
That seems really high to me.  Can this be right?
I measured from the mounting surface to a straightedge resting on the wheel
rim.

And thanks to the NeOkla region for putting on a splendid Solotime
Divisional #1!!!  What a great site to race on.
