Help ZXR250c Mystery Bolts

After putting the engine of my bike back together and putting it back in the frame I have been left with two mystery bolts.
They are both quite dirty with general road grime and grease, and they have no strength number on their head.
These where in a bag by themselves which annoyingly was the only bag that I didn't label during the tear down.
Please help me figure out where these bolts go so I can get my bike back on the road.

 

Bolts to hold your engine in ?

 

Megazip have exploded diagrams. Maybe worth a look?

The engine is all in place. There also too short for engine mount bolts.

 

I've looked at exploded diagrams and in my worshop manual and can't find them.

 

Looks like water pump bolts but there should be 3

 

Are they 8mm head

 

the water pump is all back in place.
they're a 10mm head

 

nope. I have them in a labelled bag.
and they're too long for that.

 

that's what I was thinking too. But it's got me completely stumped.

 

Front sprocket cover maybe then, although im sure there 8mm too

 

that's back on the bike too.

 

Starter motor through bolts

 

the starter is all in place
