[200q20v] Engine mount part number?

[rao at pixar.com]

Folks,

I'm in the process of overhauling the front-end of my '91 sedan, and
just discovered that the passenger-side engine mount has a different
part number from the driver-side mount.  The Parts Connection lists the
same for both (as apparently does catalog.exist.ru): 443 199 382.

The drivers-side mount that I took off the car has that part number, and
a green dot.   the passenger-side mount has a different number and an
orange (or brown dot).

Anyone know what the deal is?  Any help would be appreciated ...
