With the Gibb novas there is around 50 cars between each VIN# There is 4 different sets of body #s. But the thing I found out is some of the early body #s are on later VINed cars. I thought for a long time that the 4 body #s where related to the 4 colors of the cars. One car showed up that proved that wrong. 20 years of study these cars and still dont know how they were done??
AS the saying goes the more you know the less you know.
