I agree with Pete, turn the joint side ways to take the load and the other trick is to use a BIG rod end, 3/4 inch minumum and buy a premimum part, not the $10 ones that work for steering shaft supports. I use a "wish bone style locator on my streer roadster and the rod end is a 3/4 inch, aircraft quality piece that I paid about $75 for a number of years ago. (I never throw anything away!) Remember where ever the rod end is mounted to your rear housing that is the roll center. So you can do it high or low. My preference is like Pete's, low.
