In search of the "Holy Grail"

[70Custom10Nut]

Question for all.
What do you consider the "Holy Grail of Junkyard finds"? Mine used to be a Tach equipped Dash Cluster until I happened upon one in the corner of a little place I used to hunt in (the stars were in line that day).
Then it went to a tilt steering column til I found one on Ebay (I still look for them though). Now it's the stainles drip rail trim. I know any of these things can be bought aftermarket but it's just so satisfying when when you rub the mud off a window, or pop a hood open and you find .........
I will forever hunt the yards for stuff, because just buying new parts just doesn't have the same feeling of satifaction.
