Terry I think you are going to have to rely on your ingenuity to integrate Clansman into your vehicle.
I think I have all the Saracen installations in EMER COMMUNICATION INSTALLATIONS, they are exclusively Larkspur. Indeed the detailed index of A001 lists nothing else but that system. These of course are EMERs I have no idea if something might cover what you want in an EMEI (AUS) of those that I have only Larkspur is covered.
Is this of any help?
If you take a fancy to a particular Larkspur layout that you feel would lend itself to being the basis of a Clansman installation then choose something from the list below. The relevant EMER CI gives a fair number of diagrams & photos.
