Where to find DOHC CB750 swingarm thrust?

Hi, in my process to rebuild my DOHC cb750f, however found that I'm missing two swingarm thrust. Did my research and found that it'd be very dangerous without them as the swingarm would go side ways and therefore cause a speed wobble. The parts (52109-425-831) are no longer available from all the resources I know. Could anyone tell me where can I secure a pair of these or if there's other substitutes?

This guy has 2 at $19 each.
