@sammys Hello, and welcome to TheRangerStation.
That is a nice Ranger you have; I'd love to have an '83 diesel myself, and they are not common at all. That's not a bad job on the turbo installation, either, and it has to make it more fun to drive, too.
Resources like option build figures on the earliest Rangers just aren't readily available. I've yet to find, in casually searching the internet, even what the total number was of Rangers built for the 1983 and 1984 model years.
It looks to me that over the years, previous owners may have upgraded the original truck. The Eddie Bauer trims are from a Bronco II, as mentioned. That style of wheels were first offered for the 1988 model year. And the power locks and power windows, as best as I can determine, didn't start until the 1985 model year in the Ranger.
Does your driver door still have a "Safety Compliance" sticker on the rear of the driver door? If so, what is the build date ("DATE" upper left) and does the VIN match your dash plate VIN? It wouldn't surprise me, that at some point a Bronco II Eddie Bauer package donor vehicle provided a previous owner with a lot of "goodies" that were transplanted to the '83 Ranger. The outside paint on the passenger door even matches the B2 EB two-tone paint schemes; and it would have been easy to swap both doors, including the wiring.
In any case, it's a very nice truck, and probably has an interesting history. If it were to be fixed up just like it sits now (body work, new paint, etc.) it would make for a great and unique classic Ranger.

definitely drive it!
