Thanks 68Jim. As I said we found the core support # But nothing in trunk. We took it down to bar metal. As heavy as that # is stamped it would be easy to see. This VON # was it just a random # or is in some way tied to the VIN#. In other words say your VIN# was RS23L8A100001 did they use just a random # or did they know VIN# 100001 would be specific VON#100100 then VIN# 100002 would be 100200. and so on or was it just a # pulled once the car was ordered?? If its just a random # not sure why they bothered. If a car was hit front and rear drivers side you could loose both #s in 1 wreck!!!!!! Thanks Larry J
