I own a 1984 silverado pickup. One of them big plastic shield/covering deals was off on one of the tanks on my pickup, so I just took the other one off. Are they really important? I supposed to protect against rocks and stuff maybe? but I don't really do any wheeling like you guys do, like hardcore stuff, the wheeling I do comes when I'm hunting and fishing, and I am usually pretty gentle. also, when I put headers on my motor, I took off one of the bumpstops. Should I do some cutting and stuff and find a way to put it back on? are they that important? thanks for the help, this is definetely the best automotive site i've been on.
