It may be written somewhere in my BMW 27 volume workshop manual. (sorta fell apart over the years, the manuals more rooted than the bike)
But regardless of what I may or may not have written, as soon as your uni is on the bench in front of you, you will have your sizes and that is as good as a part number.
Just a standard universal joint. Even comes with a grease nipple but I think I took mine out. Sure as hell never greased it!
Don't even need to take the uni out of the shaft to measure and could be done in the bike prolly.
Oh yeah, there's a little peening to help keep the lid on things.
Edit, that's 100,000 k + repair.
