Wishbone ball joint diameters?

[-Welsh-Stealth-]

Was tracking up my car this weekend just gone. And noticed the near side front lower wishbone/suspension arm ball joint rubber had split. Ball joint is perfectly fine& still doing its job, but obviously now a split rubber is an MOT fail. Also want to get it covered up before anything other then grease gets in there.

So does anybody have any ideas on the diameter of:

 

Top hole mm?

Bottom hole mm?

Uncompressed height mm?

 

Or have a wishbone laying about they could get the measurements from? It would save me taking things apart just to measure& put back together until the right size dust covers arrive.

Any help greatly appreciated!
