i think mine is june. which is better for the convertion early or late?

if it's made after July '76 it is...

if it has a Borg Warner 68 Diff (removable back plate) most definitely

however the 1971 model (aussie assembled) Datsun 1200 4 door sedan also has a BW68...

my 120y is a 1976 model (4 door sedan). is that an early or late model

This site is great for bringing old memories back! I recall about 15 odd years ago wrecking what we thought was a 240K, but it had badges on it "2000 GT". This thing had a 2 litre six cylinder in it, the engine was an L20A.

the Personal Six (Cedric) of the mid sixties used a predecessor of the L series that Nissan inhereted from Prince in their merger, not sure of the designation though. They had both 4cyl and 6cyl variants. The '69 on models were released with L20A in some variants.

the other vehicles I know that the L20A was fitted to were some Nissan Fairlady Z's, C110, C210, and R30 Skylines. I suspect it may have been the engine in an obscure 610 model that was released with a 6cyl L series, but I haven't been able to find much about that car. there were probably other models it was released in as well.

Quote:At the risk of being critiqued again for setting the record straight, the Datsun 200B is the 810. The 710 was not marketed in Australia & it looked quite similar to the 180B [610]

I had always believed that the L20 [six] was used in the 'Datsun Personal Six' of the mid/late 60's. I once worked with a bloke that owned one. This engine wasn't known as the L20A untill after the L20B came into being, & even then, I'm not sure that this is a factory designation, but more a replacement parts industry one.

The problem with an L-six in the 120Y is not so much weight, but length. The L-four is a better choice all round.

Stick with the conversion. From all acounts, this is becoming more popular in 1200's & those that have them on the road simply love it, so I'm sure you will too.

the only difference between auto and manual 120Y shells isthe gearbox mounts...

that being said there is TWO different B210 120Y floorpans...early and late: the seats don't intechange between the two...

will the gear box fit in the tunnel? or will it need to be bashed abit

the two unused crossmember bolt holes?? (the ones at the front??) they are used for the 180B Cross member

200B (710) and Bluebird (910) are identical apart from the fact that the bluebird has rack and pinion... but they don't bolt straight in....
