Recently purchased a 00 NHRA T/A that I already know is 1 of 110 but I am trying to find out which of those 110 or so it is. I thought that since it was a factory option that they might not have kept track of them, but I have run into guys with ls1 ws6's that have found the production number of their car So I am assuming that they would have kept track of the NHRA cars like the did the ws6 cars because you could get only one package or the other, not both. Any info is greatly appreciated.
