If you want a true price comparison you need to factor in the cost of replacing EVERYTHING on the Camaro clip, I mean all wheel bearings, seal, rotors, calipers, control arm bushings, ball joints, tie rod ends, idler arm, steering box, brake pads, and hoses!
It really adds ups when you think of all that will need to be replaced 30-40 year old subframe versus a new everything included MII IFS. And you also need to consider having to cut the front of the frame off causing issues with the wheel centering in the wheel well and core support and bumper mounts.
