I put 31" on the backs of all mine.
Quoted from Colsond3:AL legs, however, have an abnormal 2 1/2” spacing between the leg bolts, from center to center.
You had me so excited for a second there, but now I'm more confused. My Gamatron came with two regular legs and two legs with a 2 1/2" spacing on the holes (and only six leg bolts )
Just went to look at them though, and they aren't ribbed, and are only 28" long. So I'm still confused.
