While similar looking to the Camaro brakes the Delta 88 brakes are much bigger and you would have to adapt the ball joints and steering linkage to fit.
If you do not have access to a machine shop and welding, look for more compatable components.
DISC BRAKES THAT WILL FIT FIRST GEN CAMAROS
You can use the spindle, caliper, bracket, or rotor from:
Buick Special 69-72
Grand Prix 69
Grand Prix 70-72
Monte Carlo 70-72
Olds F85 69-72
Sprint gmc /El Camino 71-72
Ventura II 71-74
They must be disc brake equipped of course. I believe discs became standard in 1970.
Some of the cars listed have the caliper forward of the spindle. You must swap side for side placing the Caliper to the rear of the spindle on the Camaro.And use your Camaro steering arms.
I'm not shure about brake boosters working from every car listed. TheFirebird , Nova, El Camino, and Monte Carlo do for shure.
I've also deleted four piston type from this list.
