    My truck was originally an 87 Custom Deluxe 305 SM465/208 setup and had the 168 tooth flywheel, 154 is mostly for cars I believe.

    Slap a tape measure on the flywheel......the 168 tooth measures about 14" in diameter and the 153 tooth about 12".

    The starter for the 168 will work on the 153 also.

    Not all starters interchange......Stock units have different nosecones & some aftermarket units have a dual pattern.

    True, but I beleive the starter he's inquiring about is the one without the nose and dual bolt patterns. Am I correct?
    If not, sorry for the assumption
