Hi. Make all your adjustments with the tranny and shifter in neutral. There is a way to lock the shifter in neutral with a drill bit. My Duff (Hurst) shifter arms point up as in the photo. Your factory arms go to the steering column and should be removed. I think the links on the tranny are useable. Some have little bends in them that bring the linkage closer to the tranny. If you have the arms with the bends the arms may go on from the outside (arms inside is shown in the photos. If you have the straight arms, as in the photo, do it that way, from the inside. Find the correct bushings and clips for the tranny arms if you did not get them. My shifter likes WD 40 a couple times a year. Good luck
