the bell housing may be integral as on the later models or separate.

many of the flywheels are neutral balanced but you cannot be sure. mark the position before removing the flywheel from the crank you will be using. have it checked for balance. if it is neutral then your job is easier, you just need a neutral balanced fw. if it is not neutrally balanced, then you must have the new fw matched to it. it seems like maybe 70 to 80% of the fws turn out to be neutral.

in my personal experience i have found three that were neutral and one that was not.

if it is not you will have a big problem if you put on that is not matched to your crank.
