I stripped off the drum brakes from the front axle and pulled the hubs off along with the steering arms and cross link bar. I also removed the steering stabilizer shock and the hubs from the spindle.
I ordered a Pontiac Firebird Disk Rotor, Caliper and pads from Autozone to mock up how the caliper mounting bracket will need to be fabricated because no kits or upgrade packages are made for the 1966 G10 Chevy Van front suspension that I am going to try and use. I may have to have the hub machined for the rotor, I will take the rotor with me to Autozone when I pick up the items I ordered and see if it will work or will need to be cut down.
