What is the difference in Early 1963 and Late 1963 Headlight Buckets?
Early 1963 Corvette headlight buckets were originally made of fiberglass. So, our Headlight Bucket Extension Harness 617872 was designed for use with the early fiberglass headlight buckets and is manufactured correctly.
Later in the 1963 production, some experts believe sometime in January of 1963, all production Corvettes were switched to metal headlight buckets.
However, if a fiberglass headlight bucket got damaged and needed replacing, the only available option was a replacement headlight bucket made of metal.
Through the years, many of the original 1963 Corvette fiberglass headlight buckets were replaced with the metal ones. Consequently, the wiring had to be changed.
We offer a Headlight Bucket Extension Harness 617873 for those 1963 Corvettes that have the newer, metal buckets.
If you are not sure if you have a fiberglass or metal headlight bucket, put a magnet to it!
