And foget the interchange list because those cars have been crushed long ago or have been boned of disc brake parts long before the internet was invented.
Sorry to say but there still around and with the discs still on them, I picked up a 74 Nova parts car a few months ago for $500 with discs and lots of other parts
This list is just for the spindle 69 Camaro 69-74 Nova 71-74 Ventura 73-74 Apollo 69-72 Chevelle 70-72 Monte Carlo 73-74 Omega 69-72 Tempest 70-72 Grand Prix
this list is for the Upper,lower control arms and the spindle 73-74 Apollo 69 Camaro 69-74 Nova 73-74 Omega 71-74 Ventura
I didnt list any of the years before 69 because you have a 69 and thats when GM went to the single calipers And the sub frame is the same on the 69 Camaro,69 Firebird, 68-72 Nova, and 71-72 Ventura
