<VV> LM bolt pattern

Many folks have done this with no problems both inside and outside the
Corvair community, but it does make the engineer in me nervous.  If I was
going to use these, I'd make an adaptor/spacer to push the wheel out a1/4"
or so and fix the centering hole mismatch.  The additional 1/4" would allow
plenty of length to "bend" the studs without stressing them.
