Early A-Body "Over-Engineering"?

I always thought that the factory A/C under hood setup was overly complicated IMO. So many brackets and braces along with idler pulley and different crank pulley.

I think "part" of that is that back in the day Chrysler actually made refrigeration/ AC systems (stationary, not vehicles) So maybe they "knew" what it took to make stuff truly heavy duty. I can remember through the late 60's--later seeing LOTS of GM pumps WITH THE BELT REMOVED because the clutch or compressor had failed.
