As above...

The st170 is unique so clutch/flywheel and shafts will not fit anyother box and vice versa.

You need to run st170 clutch/fly standard or uprated... if uprated look from USA they call it SVT rather than ST170

Gear selector cables and stick you need st170 too!

Shafts again you need st170 set up and if using zetec block you need the sump pan as the half shaft mounts to this...
If your using cvh engine still you need to make a mount of block for the half shaft!
