ORU's boxes the frame without needing to weld it. Sky's was designed for OBS frame horns which are already boxed.
Most people box the frame and then use sky's or their own homemade rsk.
I've read of people using sky's without boxing the frame which is something I highly advice against.
Just a few holes on the frame horns if you go with the overpriced ORU.

Will also need taller lift blocks, dropped pitman arm and depending on the amount of lift either a dropped bracket or adjustable...
Checkvalve before fuel filter cured my hardstarting problems. Even with leaky returns it fires right up.
How long does the "wait to start" light stays on for? How often does it "click" under the hood after it does?

Just my oversimplified uneducated guess
