Engine + gearbox .. make sure they aint being seperated.
Drive shafts off the engine thats going in.
Transponder + ignition colume.
If like my 1.6 you have power stearing ... the power stearing rack.
if the enigne has the ABS system, the ABS breaks and calipers + sensors.
Dials / Clocks if you have them with the engine
Clips and jubile clips
Bigger battery as the 1.2 wont cope
Haynes manual would be good
Bolts + nuts of various sizes incase there is any damaged ones on the engine.
Plenty of time and cups of tea :thumbs_up:
Might be a few bits iv missed but im currently doing the same, my 1.2 8v dies on me and i got a 1.6 16v lump from NOVAROB he is on ebay and i can give you his email, he has engines in and out all the time and i would recomend him.
