Sorry about that.
It's a 66 C10, and yes, I am talking about a disc brake conversion. I read through a tech tip on this, and watched the install that included replacing the ball joints and tie rod ends. But, now I see this kit that uses the existing ball joints and tie rod ends. I'm just wondering if there is an advantage one over the other.
I have not done the disc brake conversion yet, but I plan to. I'd say the first thing to do is evaluate the condition of your current ball joints and tie rod ends. They might need to be replaced. My truck has 88K miles and my ball joints and tie rods all needed replacing. That's what I'm doing to my truck right now.
If your stuff is still good, then you might be able to save a few bucks by getting a kit that simply swaps the knuckle.
As for me, I plan to use the CPP disc brake kit. I have not decided if I want to lower my truck or stay stock height.
Can you post a link to the conversion kit you are referring to?
