Steering Rack

A fair bit of progress in recent months but not many accompanying posts, so I'll try and catch up today.

I've settled on a mounting method for the rack based on the position it sat in the frame when copied from the JZZ30/JZA80 front crossmember jig.
I depowered the rack by removing all power steering seals and valves in the rack and pinion housings.
I have had to narrow the rack body about 100mm so that it fit inside the chassis but as the inner rack itself remains the same width, I don't foresee any ill effect on bump steer or geometry in general.
This solution will require that the rack and pinion engagement range be moved 50mm to the passenger side, so I'll have to get a machinist to machine additional meshing teeth and heat treat them as necessary.
