Fender Tag help 69 barracuda

Hi folks, brand new to this site. I just picked up a solid and mostly complete project car. A low mileage (41K), numbers matching, all original 69 Barracuda at an estate auction.

I am confused with the fender tag. The decoding sites don't seam to help me much as the top line is 3 sequences of numbers and the 4th line is made up of 6 sequences of numbers.

Can anyone help me decifer the tag? Here it is:

M31 V78 EN2
C11 G31 G33 J25 M21 M25
A62 A86 B41 B51 C16 C55
B5 B5 D6B B5 526 B40299
E55 D32 BH29 P9B 390032

Thank you, I really appreciate your help.
