I'm rebuilding my small bore steering box on my 94 k1500. The ball bearings in the ball and block are two different sizes and slightly in color too. Well they all look the same color to me,I have all 24 bearings. What is the best way to distinguish the two apart. They have to go back in the block in order to maintain the proper ratio, I believe. Hopefully someone has rebuilt these things, thanks for any info.
