Next silly question V8 center link??

This is so simple to answer. The factory put whatever the hell on they wanted. Even if it wasn't for that car at the time, if it fit and rolled it got one more down the line. Iv'e pulled cars apart, and engines and had different year parts in there that weren't supposed to be there. If they run short when stuff goes down the line they will use last years parts or whatever is laying around. Typically when you look for some parts and they don't match you have to go + or - 1 year. Plus it matters what plant and what month it was made.
