AllData is worth the money...
I tried out this service and immediately bought it for my F250 as well as my Bronco. They are 87 and 88 respectively and the data in this site is GOLD man, I mean GOLD man. Check it out.
Otherwise, the government agency that does the safety thing, NHTSA, has a database that sometimes works and others it doesn't They track all of the TSB's as well as recalls. You can get the info there I am pretty sure.
