Speedi sleeve dana 70 spindle help

[ol' smokey iron]

I'm trying to decide between getting a speedi sleeve:

or a unitized oil seal i saw on pirate 4x4
https://www.amazon.com/National-Oil-Seals-370150A-Seal/dp/B001L5OVIA

if I did go with the 2 piece seal, would i need a sleeve anyway?

Considering most class 8 trucks use a unitized seal that would probably be the way I’d go. No speedy sleeve needed as long as the inner portion fits tight enough to prevent its turning on the spindle. The oil should never reach the spindle surface.

Thanks just wanted to make sure.
