YES!!! it is just that simple. almost all cars and truck built before 1985, are now know as B.C. (before computers) and the junk yards are full of them. so finding every thing you need should be easy. basically the motors have not changed much over the years, they just have added bunch more sensors
you can even get a electrical in line fuel pump that works with a carb. I know this because I have one on my 86 XJ
