Excessive play in zx 5 steering linkage

[Nellybobs]

Hi folks, Im strugling to get rid of the play in my steering linkage on my zx 5. the original plastic one either siezes up when tightened or wobbles like a dick in a shirt sleeve when its free!!

iv now got a 3 Racing ally jobby and it no better, yes its got bearings and a little more adjustment butt the play in the thing is shocking!! the play is coming from the cross beam were in screws into the servo saver and idler!! its that bad that iv got about 2 degrees toe wobbling about in the front wheels.

Does anyone else have this problem or does anyone know of a fix???? iv tried everything i can think of but cant sort it...its doin my nut...lol

Any help at all will be great....thanks

Paul
