The internals are the same (or certainly the majorty of parts are - I believe rhd and lhd use the same rebuild kits) but the box isn’t. It mounts on the outside of the frame on both rhd and lhd.
Why would you remove the engine for any of that?
- rebuild the ps pump unless you find something catastrophically wrong when it's apart
- get a local hydraulic shop to remake the ps lines using existing ends
- rhd box is the same just mirrored, if you're going to rebuild consider 105 shaft...
