Hi,
I'm in the process of taking my engine out on my terrano TD27T and RE4R01A.
I have removed the starter motor unbolted all the bolts holding the transmission on, removed the flex plate.
But i still do not have enough room to remove the 4 bolts securing torque converter to drive plate.
I cannot get anything to fit on the bolts.
What has everyone else used to undo these bolts?

Use the search function if not try again as i have seen the answer here. it was a ground down ring spanner with a bend in it or something along those lines. haven't had to part that combination only RB to RE4 which is a damn sight easier.

i have a ground down socket (both ends) for doing terranos also offset rings spanners work,

Okay made up a tool and undone the bolts pretty easy.
Putting the new engine in and finding it pretty hard because the rear plate cover is in the way. How do i get the bolts in and tighten them?
