On the chance that you are absolutely the mostest stupidest Willysnut on the planet and therefore don't have a roll bar, say for the sake of keeping your ride "original", Wx4 offers this short illuminatory video. If this is not enough, we would offer that an "all-original" Willys should be kept permanently parked so that future generations can marvel at your all-original gasoline, oil and brake fluid. You sure don't wanna use up these rare items, do ya?
