Michael, take the linkage loose at the transmission, then move the 2 arms on the transmission to the neutral position. Hold the linkage up an see if the ends line up with the holes in the shift arms. Put the column arms in the neutral position and see if the holes and ends on the tranny still line up. If not, lengthen or shorten each rod using the threaded part to make a nice easy fit. Put the rod ends back in the transmission arms. Try it out. Remember these trucks like to be shifted slowly and deliberately from first to neutral to second. Don't try speed shifting, it won't end nicely. If the shift is still sloppy or hangs up you will have to replace the bushings in the column. Kits are available from all the usual suppliers.
