Are those not barrow mounts and not the flat ones, as in a 70 Dart. I don't think you need to lift the motor that high with those. It's been a while for me changing the motor mounts on the car, with the motor in, but if I recall correctly, you can lift the motor enough to take pressor off the broken mount and unbolt the mounting bracket from the block and "K" member and reinstall the same. No reason to lift over the mount pins or dowls. Note: If you are having issues of breaking the driver (torque side) I have installed a chain over the mount, or you can speed a couple dollars more and buy the mounts with the stop plates.
