For me I think is entirely up to you if you which to include that on your application considering the fact that your CRB is cleared in here I really do no see any point expanding your ground to the uk border Besides you should no that including these might warrant a delay on your application pending when they are clear with your conviction in the UK anyway best of luck....
Like you may no am just a regular guy giving an advice

You will have to declare them, as they will find out about your convictions. If I were you I would declare them. No point in avoiding answering that question, they will find out very fast.
