I prefer SPUA myself.  I run SPUA on my off road samurai with 33s.
Isn't there already a plate on the bottom side of the axle?  If so, if you get the "U" shaped ubolts that wrap around the axle tube, you can just move that plate to the topside.

I see what you are saying.  I wonder why RRO didn't design it that way? All I can think to counter is that Glen thought that this way better utilized the strength of the factory perches underneath for a more stable mount possibly?

With it being a "bolt on" kit, that was the best way to do it, strength/stability wise.  Because with the top perches not being welded to the axle tube, they don't provide much stability/strength...just where they rest on the lower perches that are actually welded to the tube (I think I can see where they aren't even resting on the axle tube  ).  But if you would weld the top perches to the axle tube, then the flipped "U" bolts are the best way to go, IMO.

Hardly anybody does.  I believe the main reason is you can run longer shocks without having to weld shock mounts on the tube.  I like to keep my shocks up and away from the rocks and recommend putting the plate on top on SPOA builds.  Cheaper to as you don't have to replace your shocks right away.

I don't have a SPOA,
But the one I have checked out, reuse the "plate" just swap sides so the shock bolt lines up to use stock shocks.
