Haven't posted here in a while. The TT on my car is 04C which would make the body build the week of April 15 to 18, 1969. I have since learned there was no Camaro production from April 3 to 14. So I am assuming 04C builds would have moved to April 21 to 25. The casting date of the rear axle is D29, which supports my assumption. The protecto plate is dated 0422 G. The rear axle tube is stamped 0502 G1 E. Both sides have the 7206 stamped/numbered JL8 axles. This is in a factory JL8 car. I welcome any comments or opinions on the numbers discrepancy between the protecto plate and axle tube stamping. Frank
