Dumb question, but how do I know what job# I have? Thanks

 

I'm sure some one will chime in with the exact build dates for the job #s. If you still have your window sticker it says right on it. Or you can tell a job1 from two and three by the size of the front air dam under the bumper.
Job 1 is only 1 or 1 1/2" tall and job 2 is 4' tall ( I think)

 

Job 1 built January 07 - June 07
Job 2 built July 07 - December 07
Job 3 built January 08 - June 08

All dates are approximate...actually may vary plus or minus 1 month.

 

Thanks
