I've never attempted to repair a distributor before but my MSD pro-billet **** the bed on me. I'm not 100% sure what the part is called but I can get it at autozone for about $23. Here's thelink. The black piece in that picture is what split in half on my distributor. I'm guessing it's one of the magnetic pickups or something. I'd rather try and do the repair myself rather than buy a new dizzy for about $250. Currently using a stock one to move the car around
