Got a New 277UL Fan Case the other day? It even has one of the Plastic Crank Bearing Spacers in the Mag End of Case.

I would really like to find the Aluminium Crank Bearing Spacers vs the Plastic, not sure what they really call them. If you know of a source for them, or have a CAD drawing of them with the Spec's, please post it. It has a date Stamped inside in ink. It's the same Case as the Sled 277F, only machined around the PTO area for an O-Ring for using the Rotax Gear Drive.

Got to measure Case Bearing Space yet, but looks to use on PTO Side, BALL BEARING 6306TNH C3, 32mm - 72mm - 19mm, and on MAG Side, BALL BEARING 6206TNH C3, 30mm - 62mm - 16mm.

Those Aluminium - Crankcase Rings look to have a lip on them. So Crankcase Ring ID is, PTO Side 72mm, and MAG Side ID is 62mm. So, I maybe able, to just make some on the lathe, and honed the, if I can find the Spec's.
