I have an exhaust manifold stamped 105 02 01 705 01. I think it's from a 1964 Sprint GT but can anybody confirm that?

My parts manual says
1st and 4th should be 105.02.01.705.03 and
2nd and 3rd is 105.02.01.706.03 for GT, GTC & GT Veloce.

I guess the 03 on the end in my parts manual refers to the third revision?

Yeah, that's right, thanks.

2nd and 3rd have "PMS 01" stamped after the number, out of curiosity, what's that mean?

Might be the foundry and pattern number that actually made that batch?
