Welcome to the forum.
Check to see if there's 2 locations/pins that your stabilizers can attach to (an upper and a lower). If so, you'll want to make sure its in the correct location that matches the lifting of your arms. If not, they'll break since the geometry is off.
One way to tell. With your stabilizers connected and no implement on the tractor, lift your arms. If they want/try to widen as it goes higher, the stabilizers are mounted in the wrong location.
