MO WTB: 72 Q-jet #7042210 or 7042211

[Ozark Tim]

I am still on the hunt for the correct Q-Jet for my new 72 C-20, 350, 4-spd truck.
I believe the carb I am needing is #7042210 but have been told that since my truck is a four speed the number should end in an odd number instead of that 0. All that said, I have a 7042210 off a 72 parts truck that I am using on a different 72 4 spd and it has all the correct ports and works beutiful.
The one on the truck now is wrong and I want to get it close or correct.
Please help!
