Get one of the engine hoist balancers. It was one of the best tools I have bought for under 40 bucks then like you said yank it out and sawzall the hell out of it if you don't care.
Too bad you don't have the 53 F-100 that was in that movie (not the crappy one they blew up). LOL I was just listening to that soundtrack the other day.
