Many used items in our picture(s) have been cleaned and/or bead blasted prior to being photographed to show condition and detail. The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned. We do not retake pictures each time a used item sells. Pictures are a good indicator of what you will receive, but not all used parts age the same. On high dollar parts, email us and we can send a few pictures of the actual part available.
"Core" Items: If we use the word "Core" in the title of the product, the item has been deemed rebuildable, but has not been rebuilt. The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned.
