Jay,
This exchange must have been private, or on the Alpines list, as it's the
first I've seen of it.
I am not really sure which parts of that knock-off letter you wrote, but that
is some pretty serious fundamental physics you are getting into, and I am
pleasantly surprised you are discussing things at that level. Must have a
pretty good memory, unlike me.
I, by the way, am still trying to figure out what "Undo-Offside" means {9->
Does that mean I should find a stamping saying "Do-Onside" on the other side?
And which side is the "off side" if the steering wheel is on a different side,
as well as the road?
And further compounding the confusion, despite the fictional urban legend of a
Policeman directing traffic was clipped by a knock-off, causing every
beautiful winged center to be changed, why did EVERYBODY use the MG Marque
symbol for their center-lock?
That ought to allow some of the others to get in on this. {9->
