Yes they are, if you keep all the running gear that goes with the subframe, the control arms, sway bars etc. The extra bracing is for the bump stop on the lower control arm. 69s had them on hte front, 68s had them on the rear of the lower control arm. The sway bars are also shaped differently where they wrap around the front of the spring pocket becasue of the extra brace on the 69s. Otherwise they are the same.
