If you don't know already, your going to have to get a adapter for the bellhousing and the motor mounts.
Ooooor you could find a 200R4 from a GN or TTA (and TTA trans crossmember) and use that, It will all bolt up to the 400 Poncho

The trans really needs a complete rebuild to "enjoy" it properly. You could drive it normally but that would suck.

No it will not holdup in stock form and does not even fit the engine, yes you will need an adaptor plate....
