US CAR TOOL CORE SUPPORT ?

It's a structural component, so I'd weld it. Just do like the others have said, and use the weld thru primer....and then the epoxy primer after you weld it. Unless you're moving to the Pacific Northwest and using it for a daily driver, I doubt it will ever rust out. I am going to use the same part on my Duster. I hadn't planned on it until I was moving the car with a floor jack....and it slipped out from under the k frame and smushed the lower core support! :mad: :BangHead:
