Be careful with the orientation of that "resistor" (attached image on the right) - if it is the correct Runtz-style reducer there is an input side and an output side.
The one sold by Classic Parts (in my post above) is made so that it cannot be mistakenly installed backwards (and it includes screw ends/fittings). (attached image on the left)
