Hi Allison, welcome to the forum.
I'm afraid I have no knowledge of your lathe but on my Warco machine the travelling steady attaches to the top of the saddle to the left of the topslide. The attachment is by 2 bolts, one to the front and one at the back. The necessary holes have screw in blanks fitted.
Hopefully this may give you a clue where to look or someone with real info will be along shortly.
Jim
