Since it was long time ago and your green card was approved even with the record, I don't think it would be considered as the crime of turpitude to affect on your citizenship approval. Still, in Citizenship application, you state that you have been arrested and include all the court documents that you paid all fines and successfully completed your probation.
And hope for the best.
If you really concerned, consult with immigration attorney. 1 hour consultation is anywhere from $100 to $300 depends on the firm and attorney. But they will have better reliable answers to you. Good luck!
