K member for 67-72 Dart 318

'67 K-member is unique (idler arm, one year only). 68-72 were the same far all small blocks. 73-76 can be swapped in with the correct 73-76 motor mounts. Sway bars changed in 1973 (for cars so equipped), but the early bar can be used on the late K-member, but some will need the frame mount holes drilled.
