1966 Datsun Bluebird 411
.
 
 
The 1966 Datsun Bluebird 411 was the last vehicle in the 410/411 model line, but it featured quite a few changes in it's last couple of years. 
The most noticable changes were to the front and back of the car. At the front the 1966 model featured a new grille design that was significantly different to the previous models. On the older models the grille was heavilly concaved, with the middle of the grille being set well inwards from the front line of the car. On the 1966 model the new grille sits flush with the grille opening. The new grille features seven horizontal bars and has a tall and narrow badge mounted in the middle with a D in the centre.
 At the back of the car there is a new tail light design, which required a new panel for the back of the car. On the previous models the tail light had a large round stop light with a rectangular lens attached to the side of it. On the 1966 model the tail light is a rectangular shape with the ends rounded off. The badges feature a new design, with a more angular font on the side Bluebird badges. Most non-Asian markets had a Datsun badge in block letters.
Mechanically the car remained largely unchanged, with it using the same engine as the 1965 411, which was the 1299cc 67hp J series engine. An SS version was also available, which used the J engine fitted with twin Hitachi side draught carburettors that produced 67hp. The SSS Super Sports Sedan version was also available, which was fitted with the 1595cc 96hp engine from the Datsun Fairlady 1600 sports car. 
 By 1966, while the sales of the Bluebird continued to grow, their sales increase didn't match the size of the sales increase enjoyed by some of it's major Japanese competitors. Most of this was due to it's relatively small engine. The Toyota Corona, Isuzu Bellett and Prince Skyline by this time all had 1500cc engines and were comfortably quicker than the 1299cc Bluebird. The place this was felt the most was in the United States. This situation would be fixed in a couple of years by the significantly more powerful Datsun 510, with it's over head cam 1600 engine, which was being developed at the time. Nissan needed a stop-gap measure to stand up to the opposition in the USA, and what they did was rather unusual. From part of the way through 1966 until the 510 went into production in August 1967, Nissan started selling the RL411 Bluebird SSS with a lower equipment specification in the USA. This car was effectively a SSS with a P411 interior, and no SSS badges. This model was only available in America, and was marketed as the Datsun 1600. A wagon version was also offered.
 The last 411 Bluebird was built in August 1967, the car was replaced by the all new Datsun Bluebird 510.

The photo above is of 411 Bluebirds being built by the Pressed Metal Company in Australia in 1966. You can tell it is in Australia by the work wear the employee is wearing, in Japan all the employees would be in uniform, but in Australia it is apparently OK to wear a singlet and shorts in a factory.

Model Variations
 
Datsun DP411  
 The deLuxe version of the 411 had chrome door window frames and a chrome trim along the sill.
Datsun WP411  
 A wagon version of the 411 went on sale at the same time as the sedan. The wagon had a one piece rear door that was hinged at the top. Wagons have a Wagon badge on the tailgate door on the right hand side. A deLuxe and standard version were available.
Datsun DP411-L Fancy deLuxe  
 A "Fancy deLuxe" version was offered for the ladies, included bigger mirrors, a vanity mirror on the driver's side sunvisor, an under-dash stilletto shoe holder, an automatic clutch, bigger inside door handles, and an indicator that plays music box music instead of just making a clicking sound. They were all pale yellow with a pale yellow and grey interior.
 
Datsun DP411-M Bluebird SS  
 The SS was a performance sedan version of the 1965 Bluebird. Essentially the same as the deLuxe version of the 411, except that the SS has a pair of 38mm Hitachi side draught carburettors, very similar to those used on the Datsun Fairlady sports car. This increased the power to about 77hp. The SS had a 4 speed floor change gearbox and bucket seats. The only external difference is the SS badges on the C pillars.
Datsun Bluebird SSS R411 
 The SSS was a P411 fitted with the engine and gearbox from the Datsun Fairlady SP311 sports car. The trim level was similar to that of the Bluebird deLuxe, but it had a different dashboard with three large round dials. It has SSS badges on the rear pillars as well as on the grille and at the back of the car.
Datsun P411-R Two Door 
 A two door version of the 410 was also made. The 2 door is exactly the same dimensions as the 4 door, except that it has longer front doors. The seats are unique to this models, as they fold forwards to allow access to the rear seat, the buckets in the 4 doors have fixed backs.
Other Model Variations 
There were several different model variations for the 411 series, and these can usually be identified by their model code. 
Prefixes 
W = If the model code begins with a W, then the vehicle is a wagon. 
P is the code meaning 'power up', which is Nissan speak for a larger engine. If a 411 series car is a P411, then it has an J series engine, if it is just a 411 (no P), then it has the E-1 series engine. 
D indicates it is a deLuxe version 
L indicates that the car is a left hand drive version.		 Suffixes 
-R signifies that it is the 2 door model 
-L is a Fancy deLuxe 
-M means that the car was fitted with twin carbs 
-N indicates that the car has the auto-clutch option 
-T shows that the car has the 4 speed floor change gearbox 
-U indicates that it has the 4.375:1 ratio final drive. Only export models had the 4.375 final drive, so the -U also indicates that it is an export model. 
. 
Many of these codes, particularly the suffixes, are internal codes used by Nissan themselves and are not printed on the vehicle anywhere.
