[Healeys] Silly question

[Stephen Hutchings]

Thanks for all the exhaust advice. I’m waiting for my new system to arrive.

Now, I don’t trust my memory like I used to.  I’d had to take a front hub apart last fall (BJ8), and I’m pretty sure that the spacer that goes on to the hub first (not shown in manual) goes on with the concave side out, and the bearing fits up against the concave surface…but I can’t swear to it.
So, which way ‘round does this piece go onto the hub shaft?

Thanks in advance

Stephen, BJ8
