Amazon: Spicer axle support arm bushings

[65 Canadian]

Hello fellow Volvo friends.
I'm new to the Volvo community,and to this forum.
I recently purchased a 1965 Volvo Canadian 122s.
It,s essentially a 1965 amazon.
I am restoring the entire chassis and braking system.
So far everything has been going smoothly,with the exception of one thing.
I,m having a difficult time with the spicer axle support arm bushing.
The bushing itself wont seat properly when i tighten the clamp nuts.
When the bushing compresses there seems to be too much material preventing the arm from clamping down properly.
And as there was no bushing left when i removed the arms.
i'm not sure if the bushing orientation itself is correct.
By that I mean which side of the bushing faces the brake drum.
I can't seem to find any literature on these bushing.
Or a proper installation procedure for them.
Any help that someone can provide me with would be greatly appreciated.
Thanks,
Shayne.
