Will a sway bar kit for an A-Body up to 1972 fit an A-Body from 1974 (Duster) I would imagine the suspension would be almost the same during all those years. It's a front and rear bar with all hardware from Addco. Thanks
The bar designed to go through the k-member wouldn't fit workon the early design for obvious reasons but the bar designed to go under or around the K-member should work with either type K-member.
Since there were no A-bodies (the SS car not included) that came with a Dana 60 so you will likely need to do some level of fabrication to make one fit and clear the center section.
