Lew Congratulations on rescueing AE547 from OZ ! First things first,
Jack her up , sit her on 4 Axle stands, crawl under with a set of spanners and a Bloody big grease gun.
The banging from the rear or underneath, could well be loose UJ
bolts, worn suspension (Poss lack of fresh grease) or even worn splines.
As Jerry points out, the Aceca has extra insulation to the interior, and fibreglass footwells etc, Noise travels so check engine and gearbox mounts, exhuast mounts and differential mounting.
The Aceca is always noisier than the Ace, simply due to the tin top making the Aceca into a sound box / Drum, Later Acecas even had additional insulation inside the roof area to make it quieter.
Good Luck with curing the various ailments, Enjoy !! ..[
