I was looking at bolts & brackets for up front there, damn I took 10,000 pics & off those I got the location of 2, I think I'm good on the steering pump, got half the alrernator figured , I'll pull the old A/c compressor tomorrow & see if I can make heads or tails of that, I went through the book, they really don't get into mounting brackets much?
One of the downsides of the FSM is that they assume you're starting with an assembled car, which a mechanic would've been. It's far from an assembly guide. The illustrations in the parts books are much better for that, however they don't necessarily provide bolt dimensions or threads. By '73-'74 anyhow, they just give one universal diagram of the involved bracketry (despite six cylinder, LA, and B/RB using different setups) so it's far from perfect.
Obviously, if you haven't got the factory V2 compressor, all that goes out the window.
I don't know how far down you've taken the compressor, but be warned: The front bracket must be installed prior to the clutch/coil assembly. Some of the rear brackets, I believe, use bolts that also serve other purposes (oil pump cover, maybe). If I get the chance, I'll try to get some detail photos from my '71. It should be very similar if not the same, and that system is 100% unmolested.
Another caveat, which I think I mentioned: Converting to R134 requires new or rebuilt hoses, different oil, and a change in how the compressor is switched on and off. If you put it back using all the factory parts and use R134, you might have AC, but only for a very short period of time. It won't last. Check with one of the AC-retrofit outfits (Classic Auto Air, Vintage Air, etc.) to see exactly what you need to do because I'm still not sure myself.
