hard to find suspension parts 70 capri

[greencapri]

Tightening up the suspension on my 1970 V6GT Capri I'm having trouble finding an inner (manual) rack end and upper control arm bushes.

Want it to stay as original as possible but as driveable as can be so changing all the rubber even if ok to urethane. New shocks as well.

However both these parts are must do's.
Can anyone help.
