I changed my fender out recently and it was a huge pain for various reasons. (I couldn't figure out that the Fender "cowl" seal belonged at the top)
It was extremely difficult to remove as it has many of those square retainers which are extremely difficult to get out without easy access to pinch them from behind. In this case several were almost impossible to access from behind so i needed to break a couple. No big deal I can always replace them.
I could have used a manual that lists parts and diagrams anything out. Sadly the Vibe/Matrix Service Manual which has such great detail for things like the front bumper doesn't even mention the fender once! I am shocked.
Does anyone have a good source for finding out exactly what retaining clips are needed and where the cheapest place to get them is?
