They say:

We have a large assortment of Chevy Engine Components for Sale. This time, next time or any time you can be sure of one thing. WE sell only original GM parts. Usually they're used but sometimes we have NOS items.

We do not sell reproduction parts or components. When any automobile is restored correctly it meets the original factory specifications. That is to say that all of the drive train parts have the correct casting numbers and date codes that would have come on that particular year and model automobile.
