Recently I got the chance to buy a set of four aluminum wheels. They are called MOMO "Vega" dated from 1972. MOMO is an italian manufacturer - you might know their steering wheel collection. The size is 6 x 14" fitting exactly on the Alfa GT junior. I found out that the rims are rather 6.5 that 6.0 inches. This will give a good cornering stiffnes with my Barum 185/70 R 14 classic tires. There is no H2 hump - so there is no chance to use tubeless tires. The well known Alfa hub caps of the 5-spoke Cromodora CD-35 wheel are supplied with these outstanding contemporary wheels.
The wheels must be glas-sanded and re-painted. Silver paint or two-colour black/silver would be nice. Even powder coating would be possible.
