Help needed with the Fujimi McLaren MP4/6

[Joel_W]

I'm currently working on the rear suspension of the Fujimi 1/20 McLaren MP4/6, and I'm completely stumped on how to proceed with the build. Each side has 3 separate suspension components, a upper A arm, a Lower A arm and one alignment rod (?). The top A arms seems to position itself as perfectly square to the trans, but the two other pieces have no real correct positioning that I can see, and thus has a tremendous amount of flex.
How do you position these components for proper alignment? Do you glue them up now, or leave them as is until the wheel, hubs, etc are called for and installed?
Thanks for any and all help.
