It has been a while, but I have sent back muliple cores without the part number label and rec'd full credit. You might want to print a copy of the parts catalog page that shows the part number and the 3 digit code to substantiate the core. I have also used the IVH on Global-(dis)Connect to pull the original serial number from the component summary page to show that the core serial number matches the VIN and such. Even include a copy of the RO. I have not had one declined yet, but I put the effort into putting all the ducks in a row for them...
