All the frame's threads were filled with galvanizing and paint. Some were so filled it was hard to get a tap started. Once it did, it seemed to find the threads fairly easily. The galvanizing is quite soft and maleable. Plus it's a little slippery so the tap cut well.
Not all the inserts are used and because each one took several minutes to cut I used photos to mark which ones to tap. Not tapping unused inserts will keep the threads protected until they're needed for accessories.

Once all the tapping was finished, I started reattaching the running gear and piping. The rotisserie worked great in getting things lined up again. The OME springs resisted a bit. Without having the weight of the body to jack against, they wouldn't compress and the shackle angle was so extreme that the anti-inversion bolt hit the frame before the eyes aligned.

So did you galvanize the frame or not? I was confused when you were lifting up the frame to get paint inside. If you did galvanize it, why do you need to get paint inside the frame rails?
The truck is truly amazing!
