I need help getting this equation balanced through redox

H₂O + Al + NH₄ClO₄ + H⁺ ->Al₂O₃ + NO + HCl + H₂O + H⁺

2 Al + 3 H₂O=> Al₂O₃ + 6 H+ + 6 e- Oxidation
NH₄+ + H₂O => NO + 6 H+ + 5 e- Oxidation
ClO₄- + 9 H+ + 8 e- => HCl + 4 H₂O Reduction

Start with this

2 NH4ClO4 + 2 Al => 2 HCl +   Al2O3 + 2 NO + 3 H2O
