Get two blocks of wood & someone with thighs of steel, lol

. Just remember to grease the upper receiver threads & torque the barrel nut 35-60lbs, whatever it takes to line up the gas tube. On a serious note, I'd be more than happy to lend my vise block & tools to you, but I am nowhere near Rochester. Feel free to PM me if you don't have any luck locating them.
