Welcome! Should be a vin stamped to the left of the engine stamp. That would be very helpful to someone.
Yes, please post the partial VIN, and maybe even a picture. And you didn't post the plant designaion, but I'm assuming this is a Los Angeles VIN going by the date. So the full VIN would either be 124377L138643 or 124677L138643.
