I have the B&C Radiator from my rig that has no holes and cooled my 401 just fine. I would sell it cheap if you want to pay for shipping but I have a feeling that even cheap sale price plus shipping will be more than the McParts ones you show and if it gets damaged in shipping you are SOOL.
If I were in your shoes, I would get one from your local McParts with the best warranty. Then, like you said, if you have an issue, you can take it back. Use water wetter when you put it in, too.
