HEIM joints (AKA Rose joints or rod ends) are a bit of a minefield - They're illegal for road use, and thre are a gazillion grades and qualities.

Why do you specifically need heim joints?

They're not generally designed for the kind of angles and environment under a car and tend to have a short life. It's not commonly known thay they generally permit less angle "out of phase" than the stock ball joints and wear much more quickly, making them noisey and clunky. Angle can be increased with spacers, but this will seriously reduce the strength of a single shear connection (like at the pitman arm)

They are also not really designed for single shear mounting (like a ball joint) so the bolted connection needs to be very well designed to make the connection strong enough.

Personally, I'd be trying to avoid using them in a steering system at all for a car used on the road.

Just my 2C

Steve.

I run 3/4" heims all throughout my steering and have for several years without an issue. No wear, no noise, and very reliable. Plenty of misalignment for my five feet of flex(I just start to max out the right knuckle drag link end at full droop, remember I have lh drive).
Just make sure that you don't scimp in any way with steering componants, get the best that you can find and go overkill size.
To answer your question, I run 3/4" with 3/4"-16 shank, 1.5"d .25"wall DOM tube. My steering arms arm 1.5" thick 4130 steel in a single sheer with grade eight bolts with lock nuts.
You should also keep in mind local laws like was said earlier. If it isn't legel, run 1ton tie rod ends...
