This is a little old now but found some more info on the Toyota steering that might be useful down the road.
As stated earlier, there is a flat pitman arm available for the Toy steering box but it is slightly shorter. I have now found out that there is also a drop drag link available. This could help solve some issues with the drag link not being parallel to the ground, as I was told is desired to prevent bump steer.
In my case, the truck is a 1 ton and may need extra pitman length, which is not available, but a drop drag link might help. I have not measured anything yet.
Just an FYI
