Hello all. This is my second time on the Z sit. Previously I owned an 82 zx that I sold about 4 years ago. Anyhow I just picked up a 77 280z with around 53,000 miles (believed to be original). The car runs pretty good but I would like to change the plugs, injectors, wires, etc. if I remember right there was a source for injectors that were pretty cheap but the injectors were pretty good. Anyone remember? I have the loud rear end clunk so I need to swap out the rear diff mount. Might as well do the bushings while I am at it. Thoughts and a good source for urth. bushings. Will need a comprehensive manual on doing as well. Any help appreciated. I am located in Las Vegas Nevada.
