Boy O boy. I popped for new wiring harness under dash and all the engine bay. As well the one for the rear of the car. Best thing I could have done. Got mine from year one. The only thing they did not do is give me a wire for my under dash reverse light. Drove me crazy for a day then checked under the dash and seen no wire coming out their. So took my old harness and low and behold their it was. So robbed it and put it in the new harness. All is well. They are not cheap but the best thing I could have done over all. They do sell the new bulk head on classic if you want to go that route. Good luck Mate. That one has seen better day's.
