Neat forum, just found it. This is my second post tonight. I have an 85 chevy k-10, 4x4, 4.3l-6, 4 speed (1-low and 3 speed). I wanted to put in a 5 speed. I know they match the 5 speed to the 4.3l in newer models. Does anyone know if it will work with my truck? I like the mileage the 4.3l gets, it just needs another gear to work well.
