Not necessarily a recommendation - just an observation. Victory Performance (and I'm sure others) offer "ball joint ring taps". Any thoughts on tapping the upper end of the spindle for a screw-in ball joint? A good idea for aluminum?

I got the uppers out of the spindles yesterday after borrowing a tool from AutoZone. It will be easy to make a piece to press back in with the reamed taper for the Howe UBJs I have. I got rather lucky, in my scrap alum I had a machined cylindrical piece that I jacked up making and have almost thrown out numerous times - it was exactly the right size to fit around the UBJ and shorter than the piece in the tool kit or the tool would not have fit
That said, in regards to questioning if you could tap the upper, I can say it might be possible but a total PITA to figure out how to do. The Howe upper I have will not slip into the existing hole so it would have to be opened up a bit. Then tapped. That strikes me as a pretty tough item to get square; probably have to build a jig to bolt down to a table on a vertical mill just to get it set up for machining. Furthermore, the material is rather thin around the existing BJ and the overall thickness there is pretty short so getting threads in there and more than just a few strikes me as a bad idea.
