Engine bay wiring harness

If the listing only has for 72, then there must be some difference however small. When I put a new engine bay harness, I went with Evans Wiring. I called them and told them what I had in my car, what I was looking for, and they told me exactly what I needed. I think they were generally cheaper than Classic Industries and Year One. The harness fit in the car nicely. I did buy a dash harness from Year One and it was just right.
