hello every1

my mk4 escort started as a 1.3 bonus, and now currently has a xr cvh with standard 4 speed in it. i want to put either an xr or rs 5 speed in to it.

if i get the box and selector, will the 5 speed fit evrything else...i.e. gearbox cradle and drive shafts??

if so, can a s2 rs limited slip diff box be used as a direct swap with the bonus shafts and gearbox cradle?? thanx all!
