Are the mkIV seats a bolt in for the mk3? I've got a friend who will give me a set of the power mk4 leather seats..... The only catch is they are tan leather. I've been told by several that I can have them dyed the color of my interior. What do you think? Is it possible to run these seats in my 88? Will the wiring plug in......so on and so fourth. Are the brackets the same that bolt to the floor pan? Those things are super comfy, not to mention in pristine condition.
