SSI - Backdating -> Yet another question
When looking for backdating kits I have found that there is one for 78-83 SC cars and one for 84-89 Carrera cars. Basically what I want to know is: Why?
What is the difference? Are the flanges not the same for SC and Carreras? Is the bolt hole distance (up to the cylinders) different on SC/Carrera? Or is it something else that makes it necessary to have one kit for SC and one for Carrera? |

I just found out myself
 Backdating heat exchangers for SC - has 36mm tubes. Carrera- has 38mm tubes plus they have thicker flanges and a small extension (collar?) that goes into the cylinder. |

Mikkel, there is only one tube size
>38mm 1 1/2"OD Primary >34.9mm 1 3/8" ID primary >51mmOD 2" collector >42mmID 1 7/8" collector Weight 24lbs There are two different flange thicknesss, Carrera wants thick O2 is an option, but if it's missing it can be easily welded on.
