I just got an email from the seller. Here is their response:
"THERE IS 6800 ORIGINAL MILES, IT IS FROM #20 OF 547 AND WAS REMOVED 3 YEARS AGO."
That was in response to this question:
">Hello,

> How many miles are on the engine/transmission, and were they running OK when removed? What # GNX did they come from?

> Do you happen to have any more parts from it such as the dash panel (instrument panel with instruments.)?"
Anybody know the story on GNX #20 ?
