Hey Big Al.
There are a couple of tiny 'nicks' in both the crankshaft and camshaft pulleys. You'll have to get in close with a torch to see where they are, and once you've found them highlight them with some white paint, or the prefered Tipp-ex.
Then you'll have to find the representative crank and cam marks on the head and block (or are they on the back of the cambelt cover?) and highlight these also. Once you have done this the removal and replacement is pretty straightforward.
