IIRC there’s 4 large bolts attaching the fin to the fuselage. The wings have a lap joint containing 32 bolts per side which can be resistant to removal efforts!
The Horizontal stab needs all sundries removed and then is a case of sliding it through the fin in one piece.
Macclesfield College have moved theirs (J31) a couple of times and Eastern would be a good source of info.
Sounds easy doesn’t it?
