Kevncar, you have three options:

1) Order a pair of 67 drop spindles and use the rotors, bearings, and calipers off the 76 model. This is the easiest, as it reuses your existing ball joints and control arms and steering components.

2) Order a pair of drop spindles for a 76 model, and change your ball joints to 76 model ones and reuse your control arms. You'll use the 76 model steering linkage, tie rods, etc this way.

3) Order a pair of 76 model drop spindles and swap the 76 model control arms onto your truck. That way you will have the 76 model ball joints to match the spindles. Again, you'll be using the 76 model steering linkage.

I'd do option 1. It's easiest and cheapest. Actually, that's exactly what I'm doing on my Suburban. I'll be reusing my old early model control arms and ball joints and steering linkage, combined with the drop spindles for the early truck. The brakes are off the 75 though. I'll have the article written Tuesday when I get back on the computer next time.
