Dear Max,
The long bolt is for the alternator,take off your timing casing(the top casing) and about half way down you should see a hole where it should fit in. If you have lost,threaded or sheared the bolt i have a spare one for you, if youneed it.
The small nut looks about a 10mm, if you look at the water pump housing, near the water pump there might been a small threaded bolt sticking out, check to see if the 10mm nut fits on there.
Hope this helps, good luck.
