carnuck Posted November 19, 2010 Share Posted November 19, 2010 YJ, FSJ, AMC Eagle, CJ, DJ. All the same motor except emissions. You can use other years as well except '71. You can cut the crank or put a spacer on it with the 4.0L balancer. They are all internally balanced. Link to comment Share on other sites More sharing options...
