1966 Barracuda help!!

Guys, I am new to this site and a new Mopar owner as of Monday! I have tried to decode this Cuda since then and can only decode the VIN...Wondering if anyone can help with the fender tag? The numbers along the bottom are as follows:
11300014 - BP29 - P4X - SS1 B
Below the alphabet is 315

Thanks Guys!
