I recently called Nissan on an estimate for installation of a digital dash in my '82 280ZX. They said that, if I furnished the parts, the cost would be $1,500. It is my understanding I will need the dash unit, wiring harness, fuel guage and temperature guage. Does anyone know of any possible way to install this without the monumental cost of labor from the dealership? Also, where might I find these guages?
