rear tailgate hinge

Hi just a bit of back ground just finished washing an waxing the disco but when i opened the back door the lower hinge gave up the ghost. My question is how hard or easy are these to replace will be doing the upper hinge at same time aso where would be best place to obtain from? also heard disco2 hinges fit as well? thanks in advance

Just fitted a galvanised bottom hinge on my disco was easy just need someone to support the door at the right height when bolting the new hinge up

Thanks out of intrest where did you obtain the hinge from
