Be sure to get the metal plate under the chip near where the PT5 screw is before tightening

I missed this comment when I did this job but observed the same

No apparent effect on function

Successful completion of USBC in 20 minutes with following notes

1 the replacement part has to have the ribbon folded to match the original or will it foul the display case large screw. You know this when you can’t put the two big Pentalobe screws in on the final case install

2 my USBC part looks identical to the original, but the port has some motion even with the screws tight. I’m wondering about this a bit. I’m confident I did not cross thread the screws.

i measure the thickness of the original USB C port board at the two Phillips screws as 325 microns +_25 umicrons

I skipped ahead to step 25 successfully by making a secure stand for the display and being careful to not strain cables. If you are decently motor skilled this saves you 15 minutes or so. Not recommended if you live with cats who love little screws to chase

The small retainer flips up about 90 degrees from locked position

The screws go in tangent to the curve of the case. If you aren’t used to handling small hardware try turning the screw counterclockwise while you feel for the hole until you feel it drop, that means the threads have aligned. It takes only light finger torque when they are threaded correctly
