904 leaks on park cable fix

There's a gasket for the park cable housing, also here's an o ring seal on the cable which changes gears, probably just need to replace the gasket on the park lever,

you can convert but you would need a 66 transmission and all the linkages and he steering column, drive shaft, bracket which mounts the levers on etc, also you would need to drill one hole where the frame is were he brake prop valve is at.

But why do all that!, when You can buy the universal gasket material at oriellys and trace it on the parking lever housing add a bit of gasket let in dry for a bit.
