Makes it even less stress if you have the Zetec bottom end.

You need a S1 antiroll bar. Then our fabiricated mounts/brackets for the box bolt on.

The box bolts straight on to the block using decent clutch & plate etc...

The shafts are 909 parts using a two or THREE piece shaft setup.

Outer ends are 909 parts for a cossie and a RS2000 modded to fit a mk3/4 hub assembly

The only modd needed to do to the chassis is:-
The N/S chassis inner. This needs a section about 3in long, cut and then welded back together allowing a little more room for the box to clear the side.

Price depends on what parts you need i.e BOX, S1 Roll BAR, MOUNTS/BRACKETS, SHAFTS, CUPS, HUBS, BEARINGS, WELDING
