Marty, the a/c pump is an unusual one in that its on the right side of the engine, normally they're on the left and the battery is moved to the boot. Not surprised that every one I've seen has been different though, the factory a/c kits were cobbled together from parts of a few different models of the time.
 
Deano, if you need any specific pics let me know. I've got the late parts catalogue on file aswell that shows exploded views and schematics that you won't find in the workshop manuals. If you want a copy, or anyone else for that matter I'm happy to put it on a thumb drive and post it.

The google link thing might be a bit above my pay grade Deano, its still pure voodoo to me that they even go on a memory stick. PM me if you're interested and I'll get one in the post.
