Sounds like a plan- - - -just be sure and get everything aligned straight before you start putting any serious pressure on. Flying jacks and chains can get deadly in a hurry! There's nothing like watching a 20-ton bottle jack launch itself across the shop and punch a cinder block out of a wall to get everybody's attention! I've seen that happen during a frame straightening job at the family shop back in the 1950's!
