What Are You Doing To/With Your Car Today?

....waiting for the Summit order to come in to replace the pickup in MSD billet distributor, due to the rusting issue they have...sad that a $300 dizzy has this issue. Hopefully that cures the issue of car running like an old grain truck......lol.....if not, tracking down the issue is in order.
What part specifically is rusting? I have one that's a few years old. Just wondering what I need to look at, to be proactive.
