Legs or yokes? To raise front from under yoke I use standard front paddock stand (with rear). I remove the stem pin completely, put the securing(horizontal small) pin back in. Put stand under bottom yoke and use a thin nylon ratchet strap thru holes in top yoke and loop it under the horizontal bar that would have the stem pin in. The securing pin keeps the strap from sliding off. The strap clamps the stand horizon bar in place under bottom yoke. Raise the front stand carefully, jobs a goodun. Done it loads of times. Slacken any nuts and bolts before raising.
