"Intersting, but that seems quite unstable."
Not unstable at all, it has a wheel base of 21" and the legs are 7" apart at the base of the SJ.
"So you dismantled a 22 to add height to a SJ?"
No grills were injured in this build. All parts all came from my grill grave yard. Donor SJ had rusted out leg holes, so I actually rescued and gave new life to an otherwise discarded warrior. I did get the SJ from the metal recycle pile at the town dump. Total cost of bill? 88 cents for two of the three leg bolts.
