UCA bushings

Does anyone know if there are poly bushings available for the UCA axle bushings? I've seen poly bushing kits for the whole thing. But even if they come with the UCA axle bushings I don't need all the rest since the rest of mine are poly already and in good shape. Thanks for any help.

Sorry about the repeat. I guess I was still typing this when the other UCA thread was posted.
