Well, after cruising the junk yards and picking up a Nissan front rotor and looking at it compared to the K1500 rotor, I have decided to stick with GM parts and take 1/4" - 3/8" off the radius of the rotor to bring the caliper closer to the spindle. The rotor will be a one-off, but the modification will be easy and provide much better braking than the smaller japanese rotors.
Here is a
picture of the caliper installed on an AD Hub.
Here is a
another picture showing the huge difference between the Nissan rotor and the GM rotor.
I am going to pick up a vette caliper to check how hard it would be to mount a fixed caliper, if it looks too tough, the calipers I have shown are 1987 K1500, these have floating pins which should make the process of building the braket between the backing plate mounting bolts and the caliper pins easy. I'll laser burn brackets from 3/8" steel plate and bolt-up / fit-up / mig weld as required. More to come
