Is the frame for a 67 the same as a 72?

[midniteblues]

The rad core support mounts are slightly different on the 67-68.
Also the top of the frame rails in the engine bay are wider on a 67.
There is tabs welded too the front cross member for the disc brake lines. Where as the drum brake lines attach too the rear of the crossmember.
And the ps dimple.
All this can be worked around though too make any combo work.
