ok heres the deal. swapped my tranny and t-case out. dude told me it was out of a 78' or 79' pickup. everything works but i want my old 4x4 indicator lite to work. the dude who put it in said there was no provision for this and said i would have to swap out entire shift box and maybe mess with linkages. i contacted a tranny shop and and they said that the np203 has had the provision for this lite since its inception(he said 73') . if this is so what t-case did i get ? how can i i.d. it ? is it still possible to get my 4x4 indicator lite to work since all it is , is a mercury switch ? thanks for any and all help. also, i dont know if this helps, but the shifter knob has , like the ouline of a truck chasis on it and thats all.
