I'm thinking this right here for now......I won't be driving the truck except to move it from garage to my driveway and then back again. It's too late in the year to get it licensed (I would never drive it in winter).
Next summer I can replace all the front and rear end wiring and take the "full replacement advice."
What about this to just "get me by for now?"
