Need a bolt-in ball joint!

[STARION]

I'm making these tubular lower control arms (1G) but I need to find a bolt-in ball joint as opposed to the stock pressed-in one. The bolt pattern/ shape makes absolutley no difference, the only requirement is that it is the same diameter as the stock one. Please, don't post unless you're POSITIVE that you know one is the same diameter, because I listened to somebody who said X and X type would be the same, and I went out and baught them, and they're not even close.

-Thanks

Really need some help on this.....even some suggestions of a bolt-in that could potentially be the same diameter is ok, because I can go to the parts store with my caliper and measure them since I'm having no luck any other way in determining what fits. 92-95 Hyundai elantra are bolt in, but are a bit to small, mitsu montero are bolt-in, but are a bit too large, I've found both ends of the spectrum, but nothing that is right yet.
