Most Brownies are somewhat hard to find, most yards have no clue, get in the yard somehow, then look for 2shift levers, two shift rods going to unit high in middle of frame, if bed still on, look just behind cab, might have to cut shift rails with saw if bed still on, make sure to get shift mechanism from cab, get both driveshafts, too. Many have Tru-stop brake still attached, better score, new pads are available here in Denver. MN on brass or Al tag on left side.
