mounting an 83 gs1100e swingarm

i have currently purchased a 83 gs 1100e swingarm for my 76 kz900.
i was told that it was a dirrect fit but am noticing the axle from my 76 is not fitting through the swing arm.

sooooo.....

is there anyone who has fitted oneof these to a 76 and if so can you please help out a over his head amature please?

I had no problem at all, more details would be helpful, measurements, perhaps a photo

Did you get the GS axle with the swing arm?
If not you will need it because the GS swing arm is wider.
You will also need to add washers to each side of the swing arm mounting bolt inside the frame.
I am in the middle of this project myself.
I looked at past build threads to help me alot.
