I am useing qa1 3 peice rod ends for my steering system,in my Alfa Romeo spider. The steering arms have been drilled to 5/8 inch, carefully on a drill press, a long time drilling. I am useing 5/8 grade 8 bolts. I am carfull on doing this. I bought bolts long enough to make sure that any load will be on the unthreaded shank of the bolt. I am useing small 1/4 spacers as of now to dial out any bumpsteer. After full adjustment. I will remove these and put in the same length , so there will be no possibility of flexing the bolt. The reason for this question
Is my plan safe? The qa1 rod ends arm much stronger than oem ( frap ) parts. They well be using seals it's full rubber boots. This is for street and auto x used, and I take very good care of my car. I also drive along hy1 here in California, and have no desire to end up in the Pacific ocean.
What you're doing seems fine and pretty typical to me. Check out what gets used on sprint cars. - it's pretty similar.
It looks like you're using a washer on either side of the rod end which is a good idea - should the bearing ever pop out of rod end, the washer keeps it at least attached so you can safely stop.
I would replace the regular washers with “rod end” washers that allow more movement of the joint throughout its range while capturing it should it fail.

It looks like he's using a spacer and then a washer (at least on the pieces assembled to the steering arms), so there should be plenty of room for movement.
I have safety washers at home noe, that was test set up
Oddly, alfaholics in England run with out them even on race/ street cars
They are qa1 5/8 rod ends, thought about useing 1/2 ends, but steering is very important to me, so a we but of overkill is good
Make 100% absolutely, positively sure that the rod will not bind/lock throughout any point in the suspension's range of motion - turned both ways to full lock, full droop and full compression, and every point in between.
You probably will need "high misalignment" type rod ends.
Personally I'd be using aircraft grade bolts, as well.
To am thinking about high misalignment in the steering arms8
Seals it full rubber boots to cover the qa1 rod end
