1502/824 clasp-connecting link question

[frigaliment]

Hi all,

So I received a midsize SM the other day and the previous seller told me he messed around with the bracelet and lost one of these "shoulder" tubes that holds the clasp in place. I've circled them in one of the below photos. I'm googling around for parts, it seems like the link that connects to the clasp is usually built so that the clasp should fit perfectly without these round tubes on either side that holds it in place. Is anyone familiar with the different iterations of Omega bracelet/clasp connections of this era? Are these links connecting the clasp after-market parts or was this an older iteration?

Also, does anyone know where I can source some of these tubes and/or a clasp link that would fit the clasp without the tubes?

a couple of the photos below show a side-by-side with another bracelet where the clasp fits the link without these tubes to push it in place.

I went to my local AD and they supplied some tubes to me.
