armoured door plates

hi,
i've just got hold of a set of mk1 armour door plates from ebay, can any one point me in the right direction in terms of how i fit them? i don't think they'll be too hard but any pointers?

cheers

Easy…

Take off the door handle - One screw on the end of the door and one under the handle trim.

Insert armoured door plate into door.

Replace handle.
