OK, hear is my problem, I have a original 69 barracuda 383 w/ manual steering. I have been looking for a pitman arm. Every one that I buy or see says that it is for a 69 big block A body, but they do not fit the steering box. The area with the splines are always to big. Mine measures 1 inch. All others are around 1 1/4 to 1 3/16 Now I am not sure if mine is the fast ratio or if that makes a difference when it comes to the pitman arm. I have tried pitman arms from classic ind. year one, napa, advance. Even the pitman arm from rare parts isn't right, according to there measurements part # 20492 Dose anyone have any ideas ? Thanks
