Where can I get new front spindles?

Anyone know where I can get new front spindles for a 91 5.0? I've been looking and all I can find are spindles from the 5 lug conversion kits or used ones from a junk yard.

My driver side spindle is just a tad warped and needs to be replaced, you can tell from how the rotor spins, and we used a micrometer to read the measurements. Any help would be sweet.

Sorry for the delay guys.

To give you a little background. I started to get a little vibration in my steering wheel so I checked the usual, rotor, brakes, alignment, ball joints, etc. But everything checked out.

I've replaced the rotor, brakes, and bearings but I still have the vibration problem and my alignment is a tad off, were not talking bad but noticeable. So i ripped everything off of both sides and took a micrometer and measured points on the spindles, both the passenger and the drivers side. The drivers side is off a little from the passenger side. Also I notice that when I turn my drivers side wheel when its off the ground, it doesn't want to turn as freely as the passenger side.

So as a next step I said ok I'll replace the bearings and sleeves inside just to make sure. Did that but I still have the same problem. So the only thing that is left in the equation would be the spindle itself. Oh and this car hasn't been in any accidents or been hit, I've even put different wheels on thinking it might be the rim/wheel throwing it off.

So now I'm back to the drawing board because I can't find anywhere that just has a new OEM spindle. The only spindles I can find are in the kits for new suspesions etc. and they don't match the OEM's.

Any ideas on what I could do?
