it drops right in...ONCE you have tapped the extra hole out. the accord and prelude tranny mounts bolt up in slightly different places...so you have to tap the hole that is threadless to fit.
anyway you use accord axles, accord mounts all the way around, and then modify the accord harness. harness mods are:
changing the egr plug and oil pressure sensor connection, adding knock sensor, IAB, VTP and VTS wiring.
everything else just bolts up normally.
