I strongly recommend looking up what other popular cars were made with the same parts as yours. Even if a part is listed as not compatible with your vehicle, it may in fact be compatible. Otherwise you will want to call around for a pull-a-part service
As an example, I'm confident enough my steering knuckle of my 7th Gen Celica is identical to a 2009 Toyota Matrix. So rather than spend $300 for a single knuckle assembly that is definitely compatible, I opted to buy two knuckle assemblies for $160 total.
everything I learn about my car, I will try to update on my own posts for people to learn from going forward. So look at all Toyota models similar to your car and see if the part numbers on them match what you need for yours.
