Maybe this helps:

1): closer to 10", as you know all sits at an angle. UCA 3.5 deg. From CR drawings.
2): 12.38" CSX 4000
3): right
4): I would say, no. Depends on your wheel diameter and ground clearance.

The spindle in the upright is at 6.75" above the LCA mount. This brings your outer lower LCA point to: 27.5" wheel / 2, minus 6.75" = 7" above ground. This is dictated by the wheel diameter.

Your ground clearance (to chassis) works out to be 5" (perhaps 4").
The rear inner LCA mount sits sort of 1.5" higher = 6.5" above ground.

Assuming 5" ground clearance, then your differential/axle shaft outlet is 5" + 2" + 5.25" above ground = 12.25"
The center of your 27.5" wheel is 13.75" above ground, which results in 1.5" higher than the axle shaft.


I am curious myself about 9) But this can be calculated using a triangle function.
We need the length of the axle shaft. It's more like 1 mm only.
