lister d reverse rotation oil splash tray / flywheel removal

[lewis66]

i have recently been given three lister d engines one of which is a reverse rotation unit , the only part missing is the oil pick up splash tray , it's listed as a different part to the normal rotation engine but i cannot see what can be different , i want to build 2 engines from the three and have one of each rotation  , also any tips on getting the flywheel off
