I need a value on a transmisssion out of a 1968 roadrunner it is a 4 speed rock crusher?
You can buy these Re-manned Muncie 4-speeds from $800 to $1500 depending on the model (M20, M21, or M22) but just out of the car, you could probably get $250 to $500 depending on condition and model.
Nick B is in line.If you can prove it's a Rock Crusher, there's a Mopar guy out there who will buy it.Check some of the Mopar sites,Club sites ,and even Ebay for price comparisons.
