No it's installed in the correct position , the manifold doesn't really care if the vac port is in the front or the rear .

The linkage is NOT A body anything , that's a 72 up 1 piece setup and it's NEVER going to work properly, nevermind it's missing the mpar throttle adaptor and that angle for the throttle cable is going to cause issues .

It's needs Andyf's hise rise throttle adapter bracket to correct the throttle cable angle, the mopar linkage adapter and a bouchilion throttle valve linkage cable to the carb because the one piece setup is not going to work with that manifold .
