That's how I do it, 3' of 1" tube and done.Another shot of the frame gussets and front shock double shear bars. I just welded an X brace from the frame to the stock front upper mount, and flipped the shocks of course- it doesn't look like the reservoirs will hit the plastics, like on the 72"ers. If it does, I'll trim it.
Keep the brace forward and you don't need to flip the shocks.
If you want to, slide a thicker wall tube inside the frame where the brace lands at the bottom.
