Outer Limits 4x4 Board

I was installing my new t/case and t/case lift the other day and noticed a small amount of play in my uni's and figured I may as well change them. Ive given up trying to get them identified by the local suzuki and cbc shops, so Ive turned to the experts

Does anyone know the genuine or cbc part numbers for the uni's that have the internal cir-clip on the outer of the yoke? I believe they refer to these as external uni's?

Cheers

u need to measure the cup diameter and the compressed length of the uni with the caps on.
