The SR-71 Rapid Tool Express is back on the block and going back together for the last time. Stacey finishes up the frame into a rolling masterpiece with the suspension and drivetrain assembled for the last time. Then the body goes back on, and the interior starts to go together. We're talking fitting the carpet, steering column and the new dash bezel and stuffing that bezel with custom SR-71 gauges. After that, Stacey shows some tricks on how to choose the right transmission and why rechargeable power tools are giving the tried and true air tools a run for their money! It's all here and more on GearZ!
