There were 3 basic trim models: Custom, Xl, and XLT. Some of the upgrades weree exterior chrome trim, carpet, buckets seats and such on the more loaded XLT. There was also a towing package option, with dual front shocks per wheel and heavier springs. The Eddie Bauer is an upscale of the XLT with options like leather seats. IT's interesting if you can find the build sheet on your specific Bronco, sometimes they are put under the rear cargo area carpet o nthe XLT models. My 84 had a little tool box under the hood, and a neat little light under the hood, too. JSM84
