Bruce:
There are two trunk latches that are commonly used. The difference is the width between the mounting holes. One is 36mm from mounting hole centerpoint to centerpoint, and the other is 44mm. Your car may accommodate either. Correct for original cars is 36mm.
A great source for original Cobra parts is Holden Spares. Their website is
www.holden.co.uk. I bought the majority of my body hardware (it is OEM) from them. Their prices are fair, and they ship promptly. Surprisingly, although they ship from "across the pond" the shipping costs are comparable with domestic companies.
