Bolt size query.....

[dan7]

I've gone to bolt the mk1 driver's side engine mount on to my mk2 1.6 carb engine. But.......the four holes the mount goes into, are an unusual size. I've tried 10mm and 13mm headed bolts, to no avail. Could somebody help me identify the size please? Thanks

Need allen bolts ideally, the 2 rear ones are very close to the mount so it makes it hard to get a spanner on em!

Thanks for your help guys. Got a 6mm headed allen bolt from work, and it works a treat! Gotta borrow some more now! Thanks again.
