I decoded what I could from the date tag by manipulating it in Photoshop. It was a half-hearted attempt since the photo is at such miserable resolution, but I got the stripes, vinyl top (which was black as near as I can tell), engine and transmission out of it anyhow. No, I didn't save my efforts to post. The US build spec is clearly visible.

The interior is easy: Vinyl buckets with console--just like all automatics were in '74--in this case probably black, which is verified by what's visible inside the car. The only way to get a different interior was by choosing another color or ordering a manual transmission. The manual transmission made the console optional.
Get yourself a body service manual, both an original Chrysler-issued one (the reproductions are junk by comparison) and one digitally, such as the Bishko ones on CD sold on eßay. The Bishko one is nice because you can print off individual pages if you like, and if they get destroyed or lost it's no biggie. But if you've got to reference a lot of pages, flipping back and forth in the garage (think wiring diagrams), you'll be
much happier with a decent used original. OE manuals for the '74 were pretty plentiful and reasonably priced when I got mine. Obviously, you'll want to get an OE service manual as well for the non-body stuff.
