Darn... I must have missed some good stuff... I never read the posts before the last page... I think the thread started with how do I find my build #... ? I think it's the last five digits of your VIN... But then again, I'm from the South of California and we're really a bunch of idiots... I had to check the one in the windshield, then the one on the engine block, then the one on the chassis just to make sure...
