Sure grip question

You need a pair of axles or the spline ends of them for lining up the clutches.
This is for when you put it back together.

You need to soak the new plates or disk in the suregrip additive for a while.

I'm not sure but aren't the bolts left hand thread? Don't snap them off whichever thread they are.

Mark the case for alignment, with a center punch. So it goes back together the way it came apart.

Look at post 18 for the way it goes back together.

Unbolt it. Stagger the loosing of the bolts.
It should push itself apart.
Remove the guts. Take pictures with your phone as your doing this for later referance if needed.
Inspect everything.
Would not hurt to have a quart of lsd fluid to use when you reassemble.
