Matching numbers refers to original engine number and original drive line to the records of the vehicle VIN when it left the factory.
Much of that info has been deleted from Holden records.
We can’t tell you what the matching numbers are supposed to be. I don’t believe anyone can.
I know the right people at my local dealership and was able to get a build sheet for the car. That has the original engine number and trans etc fitted. However I first had to own it and then pay a fee.
