Dunno if the torsion bars would be an upgrade to the Minor in the way the Marina van ones are - unlikely, even if it is an estate, but worth taking them off too, just in case?
Take the two spd wipers with the loom and the rear wipe wheel as its the correct sweep to replace the front one.
Handbrake grip, Torsion bars but only if 1.8L, discs hubs etc for disc conversion, axle,wheels.
