The answer to this question is simple. Even though they both are huge at height... vegeta in ape form has super strength. Vegeta alone without going super saiyan is a high end 100 tonner, then add his super saiyan form which increase his strength 50 folds and then add his monkey form which makes him 10 times stronger; THEN this monkey form was in super saiyan mode... yeah, its understandable that he couldn't break it.
Even though both Naruta nine tails and Vegeta Monkey form is the same height doesn't make them the same strength level. I would go as far to say that black hair Vegeta is stronger than nine tails Naruto.
