Can someone tell me what the correct Carter carb #'s should be for a 1970 Hemi 4spd?
All I'm able to find out is 4745s for the rear and 4742s for the front. However, what should the letter / number be before these numbers?

For example...
I've read that ML9 4745s

M = Modified (71 carb)
L= Month first assembled (November 69)
9 = Year carb assembled 1969
4745S = 1970 426 Hemi Manual Trans, Rear Carb


Thank you for any assistance you can provide.
