Don't use concrete block's to hold up the truck!Unless they are the solid kind.I've personally seen the ones with the hollow's in them break!The best way is jackstand's or good solid wood blocks.Also you should be on a good concrete slab or blacktop.Soft ground can cause the blocking to shift and tip over.I just want you to be safe.If you were closer to here I'd be glad to guide ya through the repaires.But you are getting some good advice already.Tom
