go for a late model estate that has abs and all the extras

the rear suspension, the shocks go through the springs unlike a saf where the shock is behind

if you want to fit a cossie beam, i think you would have to modd the rear inner arches aswell as add suspension turrets do to different locations

everything else will fit straight in from front back, all holes are there for intercoolers already etc

wiring doesnt matter, its 6 wires to power a loom up, but on later models the plugs are in the same place as a saf so behind battery, use the main part of a cossie connector off car loom and wire it into the multi plugs of the estate loom, job done for loom.

plus with the later shells even in 2wd form, they have the tunel and notches in chassis legs for 4wd if you ever wanted to go that way
