North American VW parts data refers to about 10 different color
patterns for front 2wd springs alone. Rear springs that went along with
a given color dot pattern of fronts can have a different color and
number of dots than the fronts. VW apparently graded the springs as they
were made. The number of colored dots designated those deemed to be
close enough to each other to be used in a pair. That means that a given
spring rate and length could have 1, 2, or sometimes 3 dots, same color
but both springs in a pair would also have the same number of dots. Just
knowing the color of the dot(s) may not help unless you know what year
they came from.

Some years ago I attempted to research the various springs that were
used on 2wd Vanagons. I pulled and crudely measured samples from a lot
of years. My results were meager and confusing. I have since misplaced
my notes.

On some springs I found a 3 digit number as well as colored dots. I
believe that the combination of those 2 bits of info will define the
part number of the spring. In some cases you can use that to determine
what model they came from. IIRC, the 3 digit numbers were one of 3
choices....251....253.....255 and the dots were either blue, brown, or
yellow.
