After the last time i went to sears (i only go there for tires, and they've bought me several new hubcaps after they've used a hammer to put them back on) i noticed that the hood wasn't closing flush with the car. after some inspection, i found that the problem was a link in the hinge is severely bent. i found a local junkyard that has the part, and my question is, how difficult will it be to replace? i plan on replacing the whole mess including the spring, simply removing it from the hood and the car. is this something i can tackle at home, or would i be better off buying the used parts and taking it to my local volvo dealer?
