This, don't need to remove alternator bolts from memory, when I did mine I just un bolted the mani and lifted it up gives you just enough room to shove the ****er in there. Still a ***** of a job though, grazed more than a few knuckles shoving it in there and getting all the pcv lines, bov recirculation etc back on the silicone one with the manifold on there is no fun either Would definetely reccomend just removing the mani, unbolt, undo fuel lines, unplug harness and remove pcv lines etc then should just pull up... if my memory serves me correctly.
