Well, I seem to have one. The polarization looks like it's about 45 degrees
off horizontal and, since I bought Eagle Eyes sunglasses specifically for
soaring, I'm disappointed that I can't see the 302 with the glasses on.

So I hit on a crazy scheme... Since Cambridge is no longer with us, I'm
thinking of simply drilling new screw holes in my panel rotated by the
required amount, which I'll measure with the instrument out of the panel.
It'll look a little strange, but I'm pretty sure it won't take long for my
feeble brain to accomodate to the rotation.

Of course, before I start drilling, I'd gladly consider any other ideas.
The glasses are terrific for soaring, but I'm not terribly fond of them
outside the cockpit. Don't like the brown tint to everything.
