Wasn't really a junkyard, but I bought a parts car for $250 (77 300D), and was quite pleased as it had brand new tires, new injectors and a nice interior, albeit the wrong color for mine. In the trunk, in a bag from performance products was a new timing chain, rail, two lower guides, 5 new Bosch glow plugs, a block heater element and a 617.912 engine manual (which I would love to trade for a 617.952 engine manual)
Doesn't make up for all the $ I spent on the smoker, but it is nice to be thrown a bone now and then.
Nice deals on the 603 heads, BTW...
