A number of members have been recently asking about the location of the build date on their FJ's.
Open the driver's door, look on the face of the "suicide door" behind it, and there will be a mounted black placard. (Please excuse the PopTart crumbs on the floor.

)
On the upper right corner of the placard is your build date, designated by month and year.
(BTW, if yours has an 2006 build date, you might want to check out this thread:
