QQ: Can you guide my seller to the identity plate on the transmission?

[Busasaurus]

I don't know how to guide my seller to the identity plate of the transmission. It's a 95 3800 with the DT466. We're trying to figure out if it's the 545 or the 643. Can you help guide him to find it? Thanks!

I'll do you one better, here's a screenshot of some info that should help to identify.

The nameplate is on the passenger side of the transmission.
