ZF Steering Box Removal

[californiabristol]

The Zf steering box was finally removed, most likely incorrectly. The photo shows the current state with a spacer ring still connected to the steering box at the end of the Pittman shaft. I created a cross section drawing showing the original condition. It seems like the "ring" was actually part of the sub-frame, but it ended up stuck onto the steering box. This necessitated removing the lip
at the top of the sub-frame tube in order to free the steering box.

If anyone can clarify the actual mounting design or has an image of the
the steering box and sub-frame separated please reply!

Thanks,
Greg
