The Stovebolt Site Forums The Shop Area General Truck Talk Difference in 1969 through 1984 steering boxes

Here's all I know. I put a mid 70's C20 (3/4 ton) box in my 64 C10 and the steering ratio was almost too tight. It would react to any little movement of the steering wheel. The truck I got it from had the large split rim wheels on it so it must of had the closer ratio than the smaller trucks. Once I got used to it, I liked it,
