Where have all the Magnum parts gone?

The single plane in my photo above is the later offering from MP evident by the t/stat. It's MP P5007380AB, over the counter.
Was this intake used (installed on) on the later 380 crates? (Paging Zippy lol)

My 380 crate, shown below, purchased in 1998 shortly after they were announced has the earlier t/stat.
