Manual steering box swap issues

Sorry thread dig, thinking going manual steering as cheaper and more space, any issues with using PST box. So i need a new manual pitman arm not the power steering arm as have a brand new pitman arm

I don’t see any issues using a new PST box. You may not need a new pitman arm, it depends on if your power steering box is 73+ or not. If it’s ‘73+ then it should be the large sector, which would mean you’d need a new pitman arm for your small sector manual box. If your power steering box is ‘72 or earlier, it should be a small sector box and the pitman will swap over to the manual box just fine.
