There is a place South East of Cambridge that had a ton of older stuff. Last time I was there was 5 years ago. Huge lot with a great selection of older cars (rotting into the ground of course). He actually had a 69 Chevelle with a tach dash, I tried twice to get him to sell it over a two year period. No luck. He always said some guy was coming to buy it, even though I was standing there with cash, he wouldn't sell. He will sell parts, just don't be in a hurry.
The yard wasn't actually in the town of Cambridge, if I get a chance I'll look up the name.
