I just checked with Classic parts & these bearings are no longer available.
I recently bought 4 of these

they fit the propshaft perfectly but the bracketry needs some working on,
I had hoped to get on with this this month but this last my week left shoulder has seized up again & my left arm is virtually unusable,
it looks like I will need another operation before I can use it again.
so I’m sorry but this project along with a few others, is back on hold for the forseeable future, i’ts so frustrating!
