Yamaha 70 CES

Gents! I would need some help. I owe a Yamaha 70 CE(S) - 6J2S000984 - 2 stroke - and my drive shaft comp. is broken. Attached the picture. The serial number of the part: 6j2-45501-00. However this part is not manufactured by Yamaha any more that's why I can order it from nowhere.
The normal Yamaha 70 engines have a similar drive shaft comp but with another serial number: 6H3-45501-10 which can be ordered from several manufacturers around the world.

Do you have a guess how I can figure out the exact sizes and dimensions of 6H3-45501-10?
I just want to be sure before ordering it, it is not a so cheap part.

Or maybe does anybody have the part? Or maybe is there anybody who would buy the engine?

The standard 6h3 driveshaft will not fit the 70C as the 70C uses the small “G” series gearbox casing so the internal portion is going to be too long.

The 50G was a downtuned 6h3 60/70hp that was mated to the old 55hp G series gearbox - they produced it as a shortshaft for a couple of years in mid 90’s so the most likely driveshaft to fit the 70C would be 62F-45300-10-4D -
This driveshaft mates a 6h3 crank to a 663 set of gears so is a good bet it would fit but never tried it.
