Was looking to see how I can decode a set of exhaust manifolds. I have a set from a 1970 442 that was said to be original to the car. Unfortunately the car was rotted in the frame and also most of the floor and truck pan. Looks like 4022894 RH AP*D2 = 328 and 402295 LH *D2AB = 309. I will try and post pictures from my phone later.
Thanks for any and all info

I see the three digit is Julian date format. 309 = 11/5/1969 and 328 = 11/24/69
I just need to decode the D2-AP and D2-AB to confirm the year the manifolds was casted.
