I am pretty sure it is different. You should check with someone like CASCO tbird parts to confirm.

Still trying to get any info on the 56 bird bumper jack  Carl

I am sure the hook that goes on the bumper is different. Think the rest may be too. Had to shorten the upright on the one for my '57 to get it to fit in the space in the trunk. Not totaly familiar with the '56.

I need to know if a 56 t bird bumper jack is different from the 56 car jack,probably is but not sure   Carl
