Rearend Swap 1967
Short answer: An A-body (e.g., 1969 LeMans) rear can be made to fit a 1967, but it’s a lot of bother for a 10-bolt: A-bodies use rear coil springs, so the housing is wider and you’d cut off the coil mounts and weld on leaf-spring perches (and narrow it or run offset wheels).
- Width myth: members who measured 2nd-gen F-body rears found the overall track is the same ~60″ as a first-gen — it’s the welded-on spring perches that sit ~2¾” wider (cut and re-weld them).
- 1967 specifically: 1968–69 and 2nd-gen used multi-leaf springs, so on a mono-leaf 1967 you’d convert to multi-leaf or reuse your old mono-leaf perches (different depth).
- A 2nd-gen swap also needs the driveshaft shortened, careful pinion-angle setup, and possibly a big-and-little U-joint (if from a TH400 car). Typical add-on costs: perches ~$25, driveshaft ~$35, U-joint ~$18.
- Some go to the trouble for a 12-bolt GTO rear.
