Hey whats up guys... When I do a service on a GX, I take the 2 10mm bolts and the plastic clip out, and then remove the 4 12mms, the plastic splash guard will bend enough to get the pan out of the way, and like you said, they put a tin shield in there to send the oil right in the pan..... Of course, I dont know how easy it would be on the ground, cause i always have the car up in the air on a lift....Good Luck
