rare ss?

i just purchased a yellow 2002 monte ss pace car, and i am trying to find out how many of these yellow cars were built ,and what number mine is. here is the vin #if anyone can help me out,2G1WX15K129331774 .THANXS

There were 1150 produced. They should send you a certificate of authenticity in the mail about a month after you purchase it. It has nothing to do with the vin number. They were produced in the middle of the regular SS and the LS, not in a separate run. I am the proud owner of #437.
