depends on what series motor is in there right now, if its an A series a 120y motor should go right in and u will have to cut a hole in the tunnel for the shifter, otherwise its engine mounts and tailshaft modifications and a hole in the transtunnel

Yeah mate, that's the one. What's stopping me from putting a 120Y motor and 4 spd straight in?

is this the green one that was on ebay?

what motor does it have?

I've just bought a 1976 Datsun 620 ute and I want to change the manual shift from the column to the floor. Can anyone tell me if I can just use a bolt on shifter to do this or is it a gearbox replacement job. If so, what shifter am I looking for or what gearbox am I looking for. Will clutches interchange etc... What do I need to do. Any comments appreciated. Thanks.
