'60 Valinat: ball and trunion seal and u joint yoke caps

I ordered the ball and trunion boot from Bernbaum, but he did not have the caps that bolt the u-joint to the rear pinion yoke. Does anyone have an extra set they would be willing to sell? This is the last piece in the puzzle to having a complete and rotating drivetrain for the car. Does anyone know what other years and models have the same caps?

Thanks,
Stephan
