Big block kickdown substitute.

The problem with modding parts from something else is that they hardly ever work correctly due to different angles and movement. (lever lengths and travel)
It can be done if one knows what they are doing, but it would be WAY easier and function better if you can get the cable type from Lokar or someone.
If you do end up with Lokar stuff lube the cables before you install them, as for some stupid reason they don't do it when they build them and a lot of people had binding issues upon installation that were cured by lubing the dry cables.
