No joke! Its hard to find a parts counterperson that you can trust for ANYTHING. I used to work at a parts store, and for my age I consider myself fairly car savvy. I can tell you, you dont need to know a damn thing about cars to work at one of these places. **Funny Story** I also worked at a Honda dealership..I was just a light duty tech, but I was changing the oil on our parts truck..(A 5.3L Z71) and I asked the parts guy in house for a filter and he gave me a 5.7 one. I litteraly argued with him over it because his "Book" listed the wrong number.
To some parts guys...if it aint in the book, it aint out there. lol. Sorry for long post. Had to share.
