On the XP1000 trans, is there a spacer between the secondary clutch and the trans housing?

I just got an STM clutch that goes on an XP1000 trans for a build I’m doing and there’s a seal that looks like it has an inner lip that a spacer of some sort fits in. I know on some CVT setups that there’s a spacer between the clutch snout and the bearing in the trans. I’ve looked on a couple of web sites that have parts fiches and can’t find anything.

I guess I should probably just call STM and find out – need to order a belt for the project anyhow.
