I followed the instructions given in your excellent video for the repair.
The only sticking point was that the connector on the igniter was too thick to pass between the gas tube and the back of the oven. So, I had to remove all of the screws holding the gas tube at the back and I had to loosen (but not remove) the screw(s) at the front end of the tube so that I could lift the back end up enough to create a gap through which I could remove the wires for the old igniter and to insert the wires for the new igniter behind the tube. I then reattached the gas tube at the back and tightened the loosened screws at the front and went on with the repair as instructed.
The only other issue is that, when I disconnected the old igniter from the connector to the oven, I accidentally let go of the connectors once they were separated and the one from the cabinet pulled itself back through the hole. I thought I'd stretched it enough to prevent that from happening, but, based on results, I did not. So, be careful to make sure that the tension is removed from the wires into the cabinet BEFORE you disconnect the connectors. It was easy enough to pull the stove away from the wall and put the wires back through the hole, but I'd rather not have had to do that.
One recommendation is to use a flashlight or headlamp to provide enough light to be able to see the holes in the oven bottom when reattaching the bottom with the two screws. Looking into the holes and lining things up is MUCH easier than trying to feel around with the screws for the receiving holes.
