Beyond frustrated trying to put my rear wheel back in!!!!

There must be a special way of doing it that the spacers don't catch either the swingarm (sprocket side) or brake caliper and drop out every time you lift the wheel into position???

Even tried getting Jen to hold the spacer in place, but then it won't quite get the right position when going back in and caught on the caliper.

Please someone, put me out of my misery and tell me the knack of doing it?
