How to identify a true Spyder ?

To make sure that your car is a true Spyder and not a 'franken' one you need to check the VIN number, Engine number and the Body tag. There is also a 

spyder 143 x 175hidden VIN number stamped into the body on the pinch weld driver's side front suspension area, unfortunately you have to remove the front suspension crossmember to see it.I think if the VIN, Engine number and the body tags seem genuine than you chances are pretty good that your car might be a true Spyder.

Engine number

Let's start with the engine number first.

All Spyder engine numbers are ending with YR and the number before indicate the date when it was build. E.g. T1008YR that is was build on the 8th of october. So if your body tag is confirming that it the car was build after the 8th of october then your chances are pretty good that you have a matching engine. Usually the engine and the body was build within a month. Some cars have engine from middle of September when the body was build in the middle of october. In 1964 the engine was increased to 164CID with the same YR code. Those engine have a different cylinder head numbers (3819904) which can be found underneath the engine shroud. For more information about the engine number please refer to the Engine Number article

VIN number

In 1964 the Spyder got his own vin number. All VIN number for the Spyders produced in that year are starting with 406xxxx. 4 indicating that it was build in 1964 and 06 indicating that it is a Spyder. For more information about the VIN number please refer to the VIN arcticle

Carberrator

The Carter YH carberrator for 1964 should have stamped on the top near the bowl cover the number "0-1580". If it has been changed for a 180HP carb the numbers are 1769 or 1750.

Turbo Charger

The turbo charger should have P/N 3831691. If it has been changed for a 180HP turbo the numbers are different.

Distributor

The distributor should have the number 1110314 on it for a 1964 turbo distributor.

Body tag

The body tag is another clue that needs to be checked. 1962 and 1963 models the Spyder Turbo option was optional and hence was shown in the ACC code. The letter 'D' should be in the ACC code that indicates the Spyder option. 1964 the Spyder became its own VIN number and hence would not be part of the ACC code anymore. The style should be 64-06 or 64-0667 for a convertible.All 1964 have been build in Willow Run Michigan, which means you should be able to find a WR in the body number.

Regulator

 Another clue is the voltage regulator, they sit at about a 45 degree angle to clear the Turbo air cleaner.

Spare tyre holder

The Spyder spare tyre holder will have a dimple in it to angle the spare up slightly away from the turbo housing.

Engine Case

The 1964 & up 164 engine case has three horizontal ribs forward of cylinder #5 (right front). This way you can check if someone has planted a pre 1964 engine into a 1964 Spyder.
