Almost a perfect fit for 2002 Avalon
The only difference from the old starter to this one is the old hardware had notches for the electrical connection and the old starter had a longer terminal post so I couldn’t swap the hardware successfully.
Instead of returning it because I don’t want to walk to work again I decided to grind a notch on the new starter.
Lucky for me it worked and I don’t show up with my uniform sweaty in a retail job anymore

Invonveniencia de reconstruir piezas como arranque, alternador.
Instalé este arranque en mi Camry 2002. Traerlo por Amazon a Caracas me costo la pieza y gastos de envío $112. Hace 8 meses se reconstruyó el arranque original con un costo de $180. Se dañó y decidí comprar uno en Amazon. Fue la mejor decisión.

Perfect OEM swap
Size: (Pack of 1)
Perfect OEM swap for an Acura RDX. It's cheap and less than 5 minutes to install. It fits snugly, and it'll keep your car running the way it should.
