yeah i have been told that by mechanics that the engine bay is more like a coin pocket on some small jeans, you can barley get 2 fingers in there thats why labor cost are so high on Z's other than that I have small shop in a wherehouse that my dad owns, pretty much got every basic tool along with some specialty tools and a forklift and a chain. . . lol, i just have no lifts or fancy computer stuff right now just the old jack stands and creeper I also hear the wiring harnesses on Z's tend to have problems?
