        I am trying to decide what is the best year of Haynes Type3 manual to buy and use as a reference for my SP2.  I guess the best way to do this is to find out which year it has the most in common with and go from there.

Breaker points gap: 0.4mm
Spark plugs: Bosch  W145 t1
Spark plug thread: m 14x1.25

Gear box : 4 forward gears, synchro mesh and 1 reverse
Transmission ratio: 1st - 1:3.80
                                     3rd -1:1.32
                                     4th -1:0.89
                                     reverse- 1:3.88

Wheel base: 2400mm
Convergance (car unloaded) front wheels: 2 to 4.5 mm ( can someone explain what convergance is in laymans terms)
Main brake : hydralic operating on four wheels Front disk  Rear drum
Hand brake mechanical operating on the rear drums

Dimensions and weights

Lenght: 4217mm
Width: 1618mm
Road clearance: 149mm
Net weight: 890kg
Max load: 245kg
Gross weight: 1135kg
Max weight front axle: 500kg
                     rear axle : 670kg


Fuel tank 40 litres
Oil sump 2.5 l
Transmission 2.5 l
Steering gearbox 160cm3
Brake 0.45 l

        Some information that I have been able to gather says that the SP2 uses a standard production Variant platform with a Z-bar compensating spring to reduce the roll rate and the stock front suspension.  The car was introduced in 72 with two models available, the SP1 and SP2. The SP1 was a stripped down version which didn't  make it past the first year.  The SP2 had only 75hp so acceleration is not quick, around 19 seconds for 0-60mph, and a top speed of 100mph (I still havent decided on whether to keep it stock, or boost these numbers. What do you think?).

        Anyway, if you could suggest a good year of Haynes or any other good books that would help, it would be appreciated.
