What is correct Pitman arm for GT350

[S412gofast]

I have been researching and acquiring a complete power steering setup for our GT350 #1341 as it was previously converted to manual steering.

I just sourced a rebuilt SMB-B box and I now need the correct pitman arm that fits the 1" secter.

What is the correct part number pitman arm?

StangersSite has a nice description page for pitman arms.
