well that doesn't look right

Technically speaking, while the 95s were more or less OBD2, they weren't fully compliant with that standard which was fine since the mandate to get to OBD2 started in 96.   But from an electroinics/diagnostics standpoint the 95s are a bit of strange beast.

Yes but if they have an OBD2 port, and you can plug an OBD2 reader into them, then they're OBD2.

what is the ''dink'' the cylinder wall,  at the bottom, near the date in the passenger side  pic?

is that from the factory?

is that a concern?
