Searching for Jeld-win WFSU1 roller assembly

I'm sorry to say that I couldn't cross-reference that number to anything. Would it be possible to see a photo of the roller in question? Seeing it out of the door will be necessary, though I know that's asking a lot. There's just no other way to ID a match.

If you're fine with that, please show me a clear picture of the back, top, and sides. I would also appreciate written dimensions. Thank you!
