A 1985 will be hard to find from surplus or a school, Government entities and schools usually rotate out old stock based on mileage OR years, so for a district to hold onto one for that long is unlikely. You'll probably find one in the private sector easier. Carb VS Injection. Injection is better in MOST ways hands down, EXCEPT to work on. If I were broken down on the side of the road, I can fix about any problem on any carb. In 1985, Fuel injection was really in its infancy, so IF you found one that old with FI, it would likely be a very simple TBI system (most of them are simple, but still efficient). Also, there are tons of aftermarket companies that make bolt-on injection systems that come with their own computers, these systems are pretty simple, efficient, and decent to work on, so that's an option too.
