So, for preparing the cardan shaft we needed:

-Original MX-41 cardan shaft

-Front half of the Crown GS121 cardan shaft

-A piece of Celsior UCF20 cardan shaft with its elastic coupling

-Machinist

-Welding, cutting and other equipment and tools.

-Lacquer paints to taste.

First we tried on the original cardan shaft and understood that a shorter one was needed.

No problem, rummaging through the garage space we find the Crown GS121 cardan shaft which is 4 centimeters shorter than the original.

The shorter one from Crown.

Then we noticed that connecting flanges and suspension were completely different, but after experimenting with reducers and figuring out that Toyota rarely reinvents the wheel somehow we weren't afraid in this case either.

Flanges and suspension fitted as if they belonged together

Unfortunately, the turning process wasn't photographed but it's not hard to understand, a transitional bush was turned which fits snugly on the splined part of the cardan shaft, while its outer diameter matched the inner diameter of the Celsior piece. Since the bush allowed for some maneuvering, the cardan shaft was pulled in, the bush tack-welded and then everything was removed and welded.

Balance weights on the cardan were not touched and all manipulations were done after the universal joint, if desired it can be returned to its original position. All that remains is to lift up the rear wheel, start the car, engage a gear and adjust the height of the suspension bearing for more comfortable positioning relative to the coupling, but this is minor adjustments in the realm of setup.
