b'XR5 TRACK-WARRIORMid-Frame Blueprints & Materials:Following the blueprints we provide, you mock up the pre-welded front clip & rear frame clip you build (both shown here in gray). Set them XX apart to define the wheelbase. Then align & square them to each other. Clamp the frame clips down to your flat, level fixture surface to test fit the body & double check the wheelbase. When all good, cut & tack weld in the center framework (shown here in colors) with the blueprints & materials we provide. After this, weld up the mid-frame & begin roll cage installation. Cut out & cap this section after completion, for exhaust pass-thru in tunnel.
