When I was 16 I had a Datsun tryck that I used to beat the crap out of.
1952 cc motor weber 32/36 dgev carbs, thunderbird headers, totaly tricked. I wanted to take out yhe helper leaf spring to soften the ride. Had it up on jack-stands, axle detached, pounding on the frame that I has twisted using a sledgehammer. My mom comes out of the house hollering about all the noise, I crawl out from under the truck. BOOM the truck came off the stands.
