75 Borg Warner Casing Numbers

[Alger R.]

Can someone help with the embossed numbers found in several areas on my 75 4 spd Transmission (My car build date was Apr 2, 1975). On the left side of the main casing, I have the correct Stamping of my V.I.N.(15S421273). and also WC 452 (Mar 4th, 1975, Close Ratio). On the Right Side of the Main Casing I have a casting date embossed (1-8-75).
The other Large embossed numbers, I cannot decipher.....The Right Side of the Main Casing upside down from the casting date is 13 04 055 903 and below it is W.G. DIV and below that is a staggerred F C P 1..... On the left Side Cover is 13-04-097-901 and above that is Q 2.....On the Rear Housing Left Side is 13-14-066-901 Above the numbers is the Borg Warner Logo and below the numbers is a C/O Logo. Any help in better understanding these numbers would be appreciated.

Thanks, AL

Thanks for the compliment but I'm hardly an expert. Experts make $ of this stuff...students of the hobby just know alot and pass it along to others.
