$35 Electric Power Steering with Fail-Safe - No eBay module and no caster issues!!!

Oh ok, so get a power box just for its ratio and use it like a manual box with no hydraulics hooked to it. I think you can now buy brand new 16.1 manual boxes though.

I have a 16:1 manual box from PST. Effort is manageable but I want to do this conversion to make it really nice.
