Ball joint splitter, Required Width.

I'm having trouble locating a splitter that is wide enough for the joints on my 1997 Wolf steering linkages.
Can anyone point me at a model that is known to work please?
TIA.

The one we use is in the garage is a sealy fits modern cars and have used it on my P6 and series 2 restorations...

Pretty much any of the general car ones will work, but the tapered fork splitters have a tendency to damage the joint rubber gaiters.
You can buy ones that force the tapered part out, or just do what most people do and remove the nut and hit the side of the arm where the tapered part passes through, few good hits and pop shes off.
Bigger the joint bigger the hammer.

Use two large hammers and strike the arm either side at the same time
