Below is some additional info on the ball joints, its a reply from Lee in a email conversation we had about the 350 ball joints ( was picking his brain) maybe this will spark some more ideas or discussion.

My basic opinion - find a sutible ball joint and weld on a holder for it. Not pretty but the arm was junk to start with. I will leave it up to you to load this on to the BB if you like (you can edit it and take credit if you like haha).
Hoser,
The FL 350 front ball joints are not replaceable (in the normal sense of the word replaceable). The outer housing of the ball joint is part of the arm forging and the guts of the ball joint are installed, then the arm is pressed in (riveted over) to hold it all together. If I say it is not replaceable some one on the web is bound to say you can do it. Good for them.
It may be possible to set up a jig to weld on a new end to the arm. You could cut off the old ball joint housing and machine up a ring to hold one of the new utility ATV ball joints. Drop everything in to a jig and weld it. Maybe add two gussets to increase the strength. I would test it to see if the weld is strong enough to bend the arm. I would not recommend this on a part with any 'life' left in it, just in case it's not one of my 'good' ideas. Of course once some one sets up to do this at a reasonable cost one of the scamsters will copy it and you will never recover your R&D cost.
Just FYI, If you wanted to try and rebuild the joint the ball joint stud is a 'SA0' part number (the center 3 digits in a Honda part number tell what vehicle the part was originally designed for). It took a little digging but that is a '80 to '83 civic part number. I do not recommend trying to do so thou. The metal housing is forged then riveted over. Trying to bend it back and re-rivet it seams like too much bending. If you try to weld the cap back in place it is likely the plastic insert will melt. Not good options either way.
