My Lucas data sheets tell me that a Lucas 9H horn was fitted to a 1969 4/4, I'm sure Google images will provide the necessary pictures!
Mounting, my 1972 4/4 has it under the cowl box and my 1968 Plus 4 has one on the bulkhead!!
Door skins: the old steel ones measures out at 0.036 or 20 SWG
Not sure what the ally equivalent is, slightly thicker I suspect
Cheers
