That is the one I start with, then go to number 1 furthest one to the front. It is tough just takes patience and getting those two out of the way before the cussin starts helps. Also the ratcheting box wrench helps with removing, reaming and replacing. I also tie a thread around the reamer in case I loose grip and it falls, as it never drops to the ground usually winds up wedged and need to get at it with a telescoping magnet without the thread.
