1971 340 3-speed manual Duster Radiator CORRECT??

Hello I have seen the post of the radiator numbers and some radiators seem to be missing, so I'm asking here.
My 1971 Duster 340 3-speed MANUAL was built October 1970 and currently has a 1972 radiator part #3574628. I want a correct radiator for my Duster.

The build sheet is missing the "RAD" part except for the last part digit of 5. So my build sheet states my car was equipped with a radiator ending in number "5"

I have seen numbers with #3443975 last digit of "5" be a 1971 340 but with an "auto" transmission, my car is a 3-manual.

The other "5" last digit i have seen are #2998945 for 1970 auto/manual but with N51 (max cooling system). (My car is not coded for N51)
ANY IDEA on which radiator is correct for my car???
