Found a car for parts...

If I was a betting man, and I am, I would guess that the old C has a suregrip rear in it. Most of the high trim models from those years did, although it will probably be a 2:76 or 2:94. Jack it up and check, and report the good news. It will also probably be a 489 case unless it is an early built car. Nice find, the 440 could be the 375 HP motor also, they usually put them in the high trim C's. Also check to see if it has the C-body HP exhaust manifolds, they are worth $150.00-200!! Good find!!!
