Unless you can find a serpentine crankshaft pulley and maybe idler pulley, that eBay compressor with a serp pulley's gonna be hard to drive. Or, you'd have to change the clutch/pulley assembly to go V-Belt like the rest of your pulleys. It's also a "cross bolt" mount design. If you're fabbing your own bracket, you can probably get away with that. Pricing is good since it includes a lot of what you'd need.
The outfit that had the "Sankyo" compressors now has one called "Alpha" that looks like this
It has the "mounting ears", 4 on the bottom, that would drop into a bracket made of angle or channel. Like the one you found, it DOES have the "O-Ring" hose connections. Many compressors use either what I'll call a Hose Manifold that tightens to the compressor with one bolt, or you have to find port adapters to connect to an O-Ring hose end. The 6P148A used port adapters but I had them (kick again!) and mounting ears like pictured above.
