hello mate ,the conversion is pretty straight forward ,the bell housings match but you need the clutch plate from your series and the clutch backing plate from the 19j engine (plate to fit your input shaft from gearbox and backing plate to match holes in flywheel and keep it balanced),chop off your battery n air filter tray(youll probabley find the chassis rotted under it)i had to chop off both engine mountings and weld some newones on, easy if you use the long engine mount on the 19jengine(drivers side)i used a piece of 75x75 box for my new mounts just sliced it at 45deg, its much easier if you remove both wings also ,i kept my series rad and got a remote oil cooler from the scrappy and mounted it in front of radiator and replaced the oil bath filter with a k&n and moved the battery under passenger seat ,i havnt bothered fitting a fan cos i dont go that far in one shot and your glow plugs can still use the ballast resistor wiring if it was a diesel ,you will need a switched live from the battery for your fuel solenoid which is also an immobiliser if you hide the switch hope this helps if you need any more info or photos give me another shout cheers
