    Chris;
    Please supply a model & serial. We will be able to suggest options once we know what it is placed into.

    Chris;
    I did some further investigation on this issue.
    The newer DT version will physically fit the older frame, but there are major changes to the intake, exhaust, cooling and electrical systems. Therefore we do not recommend the installation.
    A Short Block repair Kit (98-3577) is still available to repair your original S4F engine.
