It looks like parts are available. Here’s the exploded diagram:

Is it item 10, 11, or 15?
Got it seated. Turns out the smaller diameter shaft sticking out of the transmission of the two in one style input shaft was the problem.
It itself wasn't seated properly and was preventing everything from being recessed the way it was all supposed to be. Thanks for all the kind words all.
no, it does not prevent it from starting...
the procedure to clear the codes does require the car to run with those connected.
@Steptoe's photos - disconnect the battery for about 30 mins or so - that will clear any stored codes
that is the only other way of doing it to my knowledge
