I cut them to be about two and half inches long, and I stuck them in the bolt holes. I got the part of the chopsticks where the diameter was a snug fit for the holes. I applied the RTV to the pan and used those chopsticks in the four corners to guide the pan into place.
I gently held the pan flush against the transmission with one hand, and with the other hand I carefully removed one chopstick and replaced it with a pan bolt. It’s a bit of a balancing act but not terribly difficult, just don’t want to smush the pan completely flush. I tightened that one bolt some but not all the way. I then removed the opposite corner stick and replaced it with a pan bolt. By the time 2 bolts in opposite corners were in place, I gave my arms a brief break and was ready to do the remainder with the pan held up by those two bolts.
