Polaris primary clutch questions.. what do I have?

[yz400ex]

I have 2 primary clutches sitting here and trying to figure out what I have and what fits what..

The 1 clutch I have, has the clutch bolt hole that measures 3/4 of an inch across. The taper is 30mm and the tapered hole is roughly 1 3/4 inches deep.

The other clutch has the clutch bolt home that measures 5/8 of an inch across. The taper is also 30mm, but the tapered hole on this one is only 1 1/2 inches deep.

My question is what clutches do I have?? What are they off of?? What will they fit??

Can anyone help me with these please. Thanks

Here is a picture of the top of each clutch to show the hole size. The clutch top plates are just set on.. not necessarily the one that goes with them..

Pretty sure I have the top covers on the wrong clutches, but still would like to know exactly what I have here and what they will fit..

Thanks.. I kinda felt left out in the cold with this question.. I was able to determine what I had though.. The one with the smaller hole in the center is for I think 97-99 700 and the one with the larger hole is for 00+ 6/7/8's. My summer was good, but the fall and so far and this part of the winter has been spent putting the sled together so it hasnt been as fun as I was hoping.. I am almost finished though and as soon as it snows again and stops raining I should be able to hit some snow.. Werent you working on a 685?? Hows that going for ya??
