Didn't Make It Home From Carlisle

The original owner was a Dodge dealer in VA. He got this 72 D100 in November of 71. It is points. I am having it towed home tomorrow from the garage a mile away so I can start to work on it. I think there is some serious damage because of the clanking noise. The noise does not seem to match the engine RPM's though. The engine starts right up.
The 'clanking' might be random detonation, also caused by a failing/failed condensor, hopefully the chain/sprocket hasn't failed....money's on condensor....
