[Elecraft] How do I know if my K2 has BFOMDKT installed?

I just installed the temperature compensated PLL reference upgrade kit on
my K2 #892.

>From everything I can see, this rig (which I bought used) has been brought
up to date in almost every way.

One step in the assembly instructions says that for S/N < 3000, make sure
I've installed the BFOMDKT upgrade, and that the kit includes a 2.7k
resistor R19 that's soldered across pins 7 and 8 of RP2 (according to
document "Upgrading the Elecraft K2 to Revision B").

My RP2 (10K) has no resistor across any pins. However, I do have L33
upgraded to the prewound 41 uH inductor, which I think was part of the
BFOMDKT.

Should I be adding 2.7k across pins 7 and 8? Is there any reason this would
not have been done as part of the BFOMDKIT upgrade?

Thanks,
