Year, engine size?
Earlys....engine can be left in but you will need to drill a hole in the box to release the clutch fork as they never come out like they are supposed to.....or if you dont wish to do that then big levers in and just muller the release bearing while the box is on its way out.
Later ones its and engine and box out job, front end comes off easy enough, rad, cooler etc but the wiring is bit of an arse. You'll need a range of jubilee cips aswell as the coolant hoses and bbost pipe.....get chopped off cos there shit.
