13 x 6 Revolutions. Very lightweight
and strong but require special
small diameter lug nut. I have a
set of these in 13 x 5 as well.

13 x 5 American Racing
Spectre. These are a dual
pattern.

13 x 5 Shelby Viper.
Libre copy. These are actually
in an early Honda pattern,
120mm but they are in such
good shape I had to buy them.
13 x 5 American Racing Libre.
Set of 4 but not the same.
Notice any differences?
The AR has a shallow front lip.
Not shown but seen in set pic
the valve stem is on the rim face.
The no name copy has a
deeper front lip. The valve
stem on these is on the rim
between the spokes. The
Shelby Vipers above are
 also this way.
13 x 5 Libre width Chipped Libre. Repairable by
good aluminum welder. As is does
not effect air sealing.
13 x5 Libre back spacing
13 x 5 Libre copy. These are 4.5 bolt
pattern, Datsun 510 and others.
All spokes were painted a
few times. 
I bought these because they
were cheap. I'll clean them up
to original look and sell them.
Bolt pattern 4.5" or 114.3mm Back space is 3.75" Front spacing
13 x 5 Libre copies. 98mm bolt
pattern (Fiat, Lotus, Triumph).
I have 3 of these. The pattern is
close and I can "slot" them to fit
a Spridget.
13 x 7 MRT racing wheels.
Very lightweight, 8#.

Libre wheel design history At left is a nice page showing differences in American Racing Libres
and "no-name" copies. His Libre shows the valve stem in between the
spokes so maybe they made a design change at some point.
