Early LT230 transfer transfer boxes don't have a cross-drilled input gear, that leads to the input splines wearing and eventually failing. Cross-drilled gears aren't available for the 1.003:1 ratio cases so FTC4993 is an oil catcher plate that channels oil down into the end of the input gear - it's easily fitted through the PTO hole with the box in situ. FTC4994 is an O-Ring needed for fitting.
