Parts manual images attached for 1974 MAR mk2, don't know dimensions other than ridiculous 12mm internal diameter.

Looking at the parts manual you need spacer tube #106659 and two aligning spacers #105604 for the rear wheel.

Google those part numbers and see if anything pops up, best of luck.

 

Possibly available from Spanish dealers but I'd be surpised if you can find one on sale. Easy enough to make or get made as it's just a tube with ID to give cleance to spindle diameter which is 12mm, OD and wall thickness to match the bearing inner race and the length is the distance between the two bearings.  The two rings 105604 fit over the tube and are to help keep it near central in the hub and lined up with the bearings so that the spindle easily pushes through. Or the OD can be made larger to help keep it centralised and machined down either end to match the bearing inner race.  All it does is stop the bearing inner races being pushed inwards when the spindle is tightened

Yes, the rear axle should have a sleeve/spacer inside the hub between the wheel bearings. The sleeve/spacer helps to prevent the bearing inner races from being pushed inwards when the axle is tightened.

The sleeve/spacer is not always included with the wheel bearings, so you may need to purchase it separately. The size of the sleeve/spacer will vary depending on the make and model of your motorcycle.
