I doubt it's sold separately. The suggestion of fixing your broken one might be the simplest way to go about it, although I would think finding another HEI core wouldn't be too hard.
In any event, I wouldn't spend too much to fix it- there are HEI distributors brand new that can be bought for <$50 plus shipping. If you have a good GM or aftermarket module, toss the one from the new distributor, install yours w/heat sink compound and call it good.
