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.

what motor does it have?

is this the green one that was on ebay?

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

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

me personally id source an L18 or L20 with 5 speed and make up some engine mounts and get a tail shaft that fits, wouldnt bother with the 120Y stuff

Yeah just bought it to teach the kids to drive in. That's why I would prefer it to have a floor shift. Not really worried about making it go fast. The motor in there at the moment looks like a 1200 from a 120Y. Has the bluey coloured rocker cover. Could be 1400/1500? Those engines you suggested, what are they out of?

if its is original it will be a j15 motor with 4 speed column shift....best thing to do is put and L16 l18 or l20b in it with a 5 speed...not much needs to be done may need to modify your engine mounts and cut a hole in the floor for the shifter

get a picture up and some of the whizz's on here might be able to tell you what engine it has
