I think that the "Build number" from the SVT Cert package is different from the "Rotation number" that appears on the sticker on the windshield. Based upon numbers I have, it appears the "Build number" is the sequence number for the Model Year build (Build#1437 for VIN 6-1570), while the "Rotation number" (ROT#3467 for VIN 6-1570) appears to be the sequence in the entire build (of 2005 AND 2006 models). I have over 100 Rotation numbers, which for 2005 models range from ROT#429 for VIN 5-0298 thru ROT#1907 for VIN 5-2005, and ROT#2039 for VIN 6-0014 thru ROT#4025 for VIN 6-2045. So Rotation numbers for 2005 models will range from around 200 up to about 2000, and for 2006 models, they will likely be a number over 2000, up to 4025. I have not been able to completely correlate "Build"numbers and "Rotation" numbers. If more Forum members send me their VIN and Rotation numbers, we may be able to develop a correlation.
