[67C10Step]

I used those same CPP spindles on my 67 for both static drop and disc brake conversion. I rebuilt my entire front end at the same time and since I purchased for 67 model all the ball joints and tie rods fit perfectly.

If CPP were smart, they would hand stamp some identifying letter or number on each after the ball joint and tie rod tapers are machined in. It would help both them internally and the consumer later on what they actually have. I also ordered through Summit in case I had any issues I'd get them involved. I had none, thankfully, so it all went pretty smooth.
