Video not available. The injection system on these cars is pretty basic and antiquated, some parts can be tricky to locate, carb conversion is simple, I'm much better at fuel injection troubleshooting or engine swapping or rebuilding an engine than I am at rust repair. If it's a good chassis and the price leaves enough room for you to financially cover some repairs go for it. if the car has rust, walk away.
