Tim. Are you saying the play is felt when you turn the pinion and propshaft back and forth or when you have one wheel jacked up and you turn the wheel back and forward without the propshaft moving?
If 90 deg of play at the pinion flange then I would not drive it any further without proper adjustment!
A backlash of .004 inches between teeth (as per Austin's advice) is equivalent to 1/16 inch movement at a radius of 7 inches from centre of pinion.
There was a works assembly jig which helped to easily set up crown and pinion meshing. I dont know how many are around in private hands I only know of one in Cornwall..see the Cornwall club site).
Crown and pinion meshing is done by a combination of shimming the crownwheel from side to side in the casing or as in your case levering round the adjusters that live under the 2 plates, one of which you can see held on by 2 screws and shimming the pinion casing in and out.
You should find engraved on the centre casing the date of the axle...that will give you the information as to which of the variants you actually have fitted.
