hi mate, welcome to the forum
Has your swing arm been powder coated at all in the past? i had mine powder coated and it all became a real tight fit when i put it all together.
I found to get it in easier, was to put something under the tyre so the spindle hole will line up with the hole on the swinger, that way you just have to concentrate on gettin it in rather than trying to lift and line it up at the same time.
I also found that putting one of the spacers at a slight angle just to get it started inside the swinger, and then push the lot in. Failing that you could get someone to try and prise the swinger apart so you can get the wheel in.
give those a go mate and see how you go.
