04L build date on 69 body tag

[Leonard]

COPO , yes, i was searching through this site to find info on a trim tag with the 04L build date. Checking to see if this question of mine could be answered in a previous post.I did compare my body # with the body # of COPO cars. Were copo cars pulled off to the side and production continued to run? Also, i take it that Vin# were in place before the trim tag. I assumed that the body tag would have been in place before it was assigned a VIN#. I still would like to have 04L question answered. Anyone? Thanks COPO
