Ball joints same top and bottom? And only available from R-Sport?

Decided to refresh my whole front suspension, starting to feel a bit sloppy and I have slight play in two joints. I know there is umpteen threads on knackered joints. But none mention of the top and bottom swivels are the same part, and if only R-Sport can obtain them? I work in a franchise that has Renault, does anyone know the part numbers for the swivels? Ferrari Piston Services do list ball joints, but no idea if they'll fit.
 
top and bottom ARE different....

top is more like an actual ball joint as the lower is more of a swivel bearing/pin assembly
 
Even with the part numbers Renault can't order the parts, Renaultsport only.

Unless you get an account with R Sport.
