i am gonna buy from prime member a newer oem knob, and shift boot, does anyone know what is involved on changing both or have a link to show how the knob and boot is changed and is it dificult. i think the knob is relatively easy but have concerns about the boot, i think changing both would look like a matched pair instead of just new knob. thanks looking forward to spring to start driving car again, these below zero temps in new york killing me
