Ahhh, the good old days of the daily repairs on a foxbody mustang. I had an 88 GT back around 2000, owned it for 7 years and it was my daily driver. Your best bet if something went in the distributor is to get a new one, MSD is what I had in mine after I put a new motor in, never had an issue (if people tell you its crap, I wouldn't listen to them, I heard the same from a couple people, but there is a reason they are used the most out of any other brand). Don't convert to carb, I've known people who did it and regret it, not ideal for a daily driver. I included a picture of my car, because I miss it, lol.
