I just bought a 1975 280z with a tired engine and 4 speed transmission, I want to swap a 5 speed, what is the easiest and best option for this transmission swap. This is my second z, had a 1976 z 25 years ago when I was just out of high school, got a good deal on it, but she is tired. As a second topic, I know I will need to rebuild this engine, any advice on what to use. It's not a daily driver, just fun on the weekends, don't need gas mileage, just fun, thanks. Troy
