Rear trunk latch
 

Has anyone out there converted the rear trunk latch from a key unlock to a cable (like the front) if so where did you get your hardware and was it difficult?

yes -

i happen to have a used cable type conversion latch available, as well as an electric one - you can buy any long choke cable from various british parts sources or your local FLAPS to hook up to the cable latch; you just cut it to lengthe once you decide where you want the pull-handle
