Don't worry about the numbers as much as the 4 letter code.

Just for reference, when I have a gm 8-digit part number that I'm trying to identify, I just Google it like "Gm 16141470" and see what comes up. Most part numbers I've tried have come up, and if you search for a few minutes, you'll figure out what it goes to.

That is the PCM itself, without the eprom, available in many cars in the early 90s. It'* the 4 letter code that id'* what it goes in, engine and tranny-wise.

Yep. Same PCM. It'* the swappable chip inside that makes the difference.
