Welcome...
This site tends to focus on the EB, I don't say this as a bad thing, it is just what the members here are interested in. There are other sites and FB pages that deal with your Generation of Bronco. Folks here do dabble in the later Gen broncos, so they may chime in with suggestions, which have been helpful since I own a 79. There is a strong possibility that the fuel rail you seek was used on other Ford products over the years, say Fox body Mustangs. You wouldn't have removed it already so that you could post up a picture(s) for comparison? We might be able to get you headed in the right direction...
