Thanks for the input guys. Once cleaned up I did find the sprocket to be a separate piece to the long axle. But it does have a centre spigot & it is the mounting face for the planetary of the differential. I really should take photo's.
The sprocket being a separate piece has made things easier, I purchased a generic sprocket with a couple of more teeth but the same pitch. only issue is it is a little thicker. Machine shop has it now to swap over the spigot & copy planetary mounting holes. because of the extra thickness we have decided to machine 1/2 of the thickness difference from the differential mounting area, this should result in a original sprocket alignment. The chain i purchased suits the new wider sprocket, I don't foresee an issue with the slightly narrower top sprocket
