Kyle : Maybe the attached will help.

Kyle - Just to make certain you don't get confused there are two pictures in Reply #4 the one on the left matches the picture of the originals in the thread I mentioned.
And for part number, since there are two highlighted the lower one (375918-S) is the one listed in the MPC as a replacement and or original as shown below. Happens to be an illustration taken from a 72 version of the MPC. Don't have the illustrated section for my 67 MPC
Sure the correct part number is right there in Jim's list
