Purchase the 22MM x 1.5 to 8AN adapter fitting from Pegasus.
Chuck the fitting in a lathe and remove the AN end from the fitting, machine the fitting smooth & flat.
Now drill the Pegasus adapter fitting and tap it for the threads of a readily available SAE spec banjo fitting of the proper size.
For a 1/2 hours worth of work you'll end up with the exact fiting you are looking for.
If you don't have a lathe, you probably know somebody who does. If not, mail it to me, I'll machine the fitting for you. Other than the adapter fitting, you'll need to purchase the banjo fitting & through bolt you want to use, plus the proper tap for the through bolt threads.
