Few Questions...

[SteveEH]

A bit late now, but why in the world would you prefer an OEM arm/ball joint assy? They're junk, good for what, 60k? Get a good aftermarket unit and be done. Also, swapping the arms is super easy, not sure what your dealer is smoking.
The GT500 arms are a good choice.
BTW, your can get a joint aftermarket for the arms......

I heard the OEM were better then the aftermarket, according to multiple people. I usually alway say aftermarket is best, but I wasn't sure on the ball joints/control arms since they come as one piece.
My Uncle and I will be swapping them in out driveway, so I guess that is why they said it would be a pain.
I also heard you couldn't just change the ball joint, good to know, thanks.
