Here is a summary of what I did to fix my Vivitar 2x Macro-TC, from memory:
First I removed the rear mount. This is necessary to remove the last element (closest to the front) without breaking it. The mount turns out to be tricky to reassemble if you have the Nikon version and want to retain aperture lever functionality, so make sure to peek in to see how all the little levers are positioned. You can reassemble it by trial and error, I know from experience 
Then there are several retaining/spacer rings and elements starting at the back, interleaved. You will need spanners like this or similar:

A suction cup tool would be helpful for getting out the elements, which don't all just fall out that easily. I actually bought one of these and forget about it, making do without. I am great at making my own life unnecessarily difficult.

At this point it looked like this and I was stuck for a while.

Now the only elements which are left are at the very tip, and are held in with an external retaining ring without a spanner slot. To get that off, you need two flexiclamps to grab the ring and the tube just below the ring, sizes 25.4mm and 28.6mm, respectively:

The ring was incredibly stiff, and some penetrating oil might help. I used thick leather gloves and pushed down hard against a scrap piece of wood to get some leverage, but eventually it came off.
Having done that, and with a bit of fiddling, thinking, and three assembly tries, I was able to get it back together in such a way that AI works, stopping down on the camera body works, and aperture readout (manual for Nikkor-compatible lenses) works. This all only worked because I didn't cut anything related, and kept all the prongs in place. I do have to use my ZF.2 lenses in manual mode for this to work, i.e. there is no electronic communication for G lenses.
I can use both my ZF.2 50MP and 100MP with this, but my ZF.2 35/1.4 cannot focus anywhere when on the adapter.
