Another loyal customer of rockauto.com.
I had to replace the brake light sockets on an older Chevy truck. The replacement sockets had an AC Delco part number, but nobody had them anywhere local. Any online search with the part # resulted in "not in stock". The dealer wanted $500 for the entire real wiring harness, and claimed that it is not only a common problem, but buying the harness is the only cure. Rock auto had the parts for $6 each. Including a few watertight butt crimps added to the bill, the repair was under $20 bucks.
It's nothing to find common wear parts are Rock Auto for 50-60% less than any local parts store, and there are often the vary same brand, or better.
