For true decifering u would need 1 letters & 4 digits where the Dash is.( thats desingnates the part series.. body trim,seat frame, etc). Henry leaves those out of most tags for they are attached to the part in ques.. But E1 states 1981 vintage for sure...could be used as late as 83-4..
I would have to venture a Guess as to interior trim as in seats or body trim of some kind for very few parts on a Ford sport a metal tag other than stuff like seats & trim. trim would have been screwed under hood & seats would have beeen wired to the back seat...ex for above would be like (what the - means) now im making this up.. 2e598 etc 1 letter 4 digits
so real part EX. E1BE 2E598 DB
date =5E212
5=1985
E=May
21=21st day
2= 2nd shift
E1= 1981
B=B Bronco, 1970-73; Maverick 1975-77; Fairmont 1978-83
E=E Engine Engineering; Powertrain and Chassis product Engineering
- = missing line code for actual Part
DB= series of part update/change
so i gonna go with seat or body trim..lol
