No idea what the diagram shows, think you need to explain better.
The camshafts and crankshaft positions are set using timing tools which only allow them to fit the correct way so you need to use the tools to get it right.
I assume the valves or rockers that were broken when the belt snapped have been replaced and that there is no other damage ? You can't just replace a broken belt on these cars without fixing the other damage first.
As above forget trying to work out cam or sprocket position invest in the locking tools. Can be had for about £15 off the bay.
Also as above unless you have had carrier off to do rockers timing belt up is pointless as it will need to come off again
