Yes, I know where 3 of them are, all are roaming around in Indy-area, one died a horrible death, another met the crusher...sometimes you don't want to find them.
Of the 3 still lurking around:
'81 Calais: Near Noblesville, IN. that last I knew. Post 260 - 350 Olds swap -wish I had this back to this day
'66
Impala: In Indianapolis, IN terrorizing the streets after ground-up rebuild. Bought it from original owners son in '95, sold it in '05
'65
Impala: Another back in Indy car; basically this was a quick flip but kind of kicking myself for letting it go so fast; this a cruiser since didn't have it long enough for a 409 swap
Won't discuss the horrible death one - let's just say,
NEVER give a relative anything, especially a car, when they don't appreciate sh*t
Crusher car, well, it did have serious rod knock and the best / most valuable thing about it were the jumper cables in the trunk
