1977 or 78 was the last year for the splined output shaft on the steering column in a squarebody. From there up to 91 is the range that can use the XJ shaft without changing the column.Is this what you guys are using for the Express "drop in" steering shaft?

And just to be clear, this is a bolt in for which year of the trucks? IIRC, one or both ends changed how the shaft mates up to the column and steering gear...?
