I'm not sure if the vibration dampers are interchangeable from 67 to 73, as some of the early 318's had forged cranks in the late 60's and changed to cast cranks in either 69 or 70 - I don't remember which year exactly, but it's not to hard to put the engine to TDC and make your own mark on the 67 vibration damper to line up with the later marks on the 73 and later timing chain cover...
If you don't still have the 70 and later alternator brackets, they are available through mancini racing or bouchillon performance in packages, some even come with the bolts...
Here's links for new alternator brackets, power steering brackets, and pulleys if you don't have the old ones from the 73 to use...
