Look at rockauto.com. I'd stay away from the kits sold on eBay at any and all costs. There will be no support when you have a warranty issue and trust me you will with the eBay kits!! Rockauto has the best prices an they are a forum sponsor. Look in the sponsor section and find their discount code.

Not sure of your location but I'm guessing it's not the US. Rockauto will ship almost anywhere I believe.

Spellcheck...

So,for the control arm. rock auto is best. like 65 each. tie rods etc,if you wanna go cheap get robestos brand parts. 6-12 bucks each. i run em and love em.

And for control arm how,do I know if I have the widerr or regular?

You have the regular.

What brand is the best for control arm?

there all pretty much the same. just go with the dorman and be done with it.
