Type of ball links for X truck?

[Evolution]

Hi guys,

I'm planning on redo-ing my x truck steering geometry with ball joints/links and just wondering if anyone can help me? I'm not sure where everybody gets theirs, but these are the only ones I know of:

These require 2/56 all thread rods. Are they too big? I want something that looks scale.

Also I've found these:

Are these alot smaller? Which one is smaller, 0.047" or 0.032"? I'm guessing 0.032"? And also, where would I find the rod for those?
