Manual for 1973 AM vantage required

[Incorrigible]

Sorry mods for cross posting this (already one in the technical forum)

I'm after a manual for a '73 vantage (I've got one for a V8 (same shape)) specifically for a diagram of how the heater/air con should be installed

If anyone could help I'd not only be very surprised, but very appreciative

This any use?

Cheers, but £70 to look at one picture of a heater that may not be the one I've got seems a bit steep

Have you tried the forums on the AMOC site?
Not been there for years, but when I was looking they seemed a friendly and helpful bunch.
