Whomever you decide to get the parts from, I'd say make sure they will be there with any support or even parts in the future!

I see folks buying parts off the big auction sites then searching for help with questions as they have no idea who made the components and that adds a lot of un-needed anxiety.

Don't cheap out with no name stuff, this is you & your family, and possibly my life, you could potentially be gambling with inferior parts! Suspension / Steering / Brakes are key areas where you need to do the best you can. (rant over.. LOL)

There's my two cents, Talk with a few vendors, ask questions and then make your selection(s). Get comfortable with them as when you may need help, you want to feel good that they will be there should you have a problem. Good Luck and let us know what you decide!
