K member removal - engine in car
I have not done this myself but have seen several articles in the mopar mags that show how. First get the car supported very well on jack stands high enough to give you space to lower and raise the k member on a floor jack. Cut some lengths of 2x6 to lay on top of the inner fender flats to spread the load across the sheet metal. You may have to remove some items like washer bottles, electrical components, ect. to give you room for the supports. You need a strong cross beam like a 4x6, heavy angle iron, box tubing, ect to use as a cross beam. You can use blocking to raise the beam up to give you room to get the motor attached to the cross beam. I would remove the carb and use a lift plate but I suppose chain(s) could be used to hang the motor from the beam. It needs to be snug enough to keep the motor from dropping as much as possible. Leave the tranny mount attached to the chassis to keep the motor in position and supported. Unbolt the motor mounts and drop the K member. Pretty simple to do.
