Inner clutch cover spacers

I’ve just rebuilt my engine on a 95 xplorer 400 4×4. Got it all out back together and my drive pulley is rubbing on the clutch cover. I’ve looked on polarisind.com and it shows spacers in between the inner cover and the transmission, I do not remember these being on there when I took it apart and I’m sure I didn’t put any on when I put it back together. Would not having the spacers cause the case to rub? Its rubbing on the front towards the bottom of the cover. I don’t see any laying around that I would’ve forgot, so does anyone know how thick the spacers are? Im sure I can come up with something just don’t know how much is needed. Thanks.
