This is a NOS (New, Old Stock) control arm to spindle support for the Right rear (passenger side) of a 1963 to 1982 C2 and C3 Corvette. The cast number is 348103 NF with date code L217 and has GM3 cast into it. The pictures show the D shaped hole clearly so you can verify fitment. The cast number is the same for both sides, but the right side was part# 348104, superceded from 3820644

This part was found while I was cleaning out an old cabinet in our GM parts department.While investigating the part, the GM parts catalogs say this part fits from 1963 to 1982 Corvette models.
 The packaging was no where to be found, so I had to research to find the correct fitment information. I inspected the part closely to verify that it has not been installed, no bolt marks,There is some red grease on the inside, I cannot guarantee that it is factory or not as this part has been here longer than I have. Photos are of actual item you are bidding on, with photos of the mounting areas to show there are no bolt marks..
There is some surface rust, but no crusty or flaky rust, so it could be easily cleaned up with a wire brush. This part has been discontinued since 1995, so a new original is bound to get harder and harder to come across.

This part will be shipped via the most economical method, usually UPS, but might also be USPS Ground Advantage or Priority, or FedEx Ground. Depends on price and speed.
