Dana 70 rebuild: does this gear pattern look good?

Rebuilding the Dana 70U in my '90. Does the pattern look ok? This is my first time setting one up so I wanted to get some expert opinions.

Here's the drive side.


And here's the coast.


I'm specifically concerned as to whether or not there's enough clearance at the top of the teeth. Any input is appreciated!

Typically I check everything and try to get it in spec as much as I can. Then I put everything together while in neutral I roll the vehicle back and forth. This would be the true contact pattern and is what you want. With those pictures above, I would guess the pre-load will actually fall inward a bit. BUT you never know, could toe in/out.

Oh ok excellent. That was just from me turning it with wrenches. Glad to know it's good though. Thanks for the reply.
