My dad has a 84 mustang converted 4 banger, and the dash is shot. It is busted cracked and the gauges dont work at all. Anyways he really like the 87-93 dashes with aftermarket gauges will they go into a 4 eyed car with no problems? Is the wiring the Same? What else needs changed, for it to work? I can get a donor car's dash for cheap but i want to know how hard the wiring is gonna be, i took the dash out of my old 85 so I know it is a lot of work but if it isnt that bad then i will consider the swap, Thanks for helping
