Details:

All hoses are used, dirty as removed, the only issue I see is with hose that goes from power steering oil cooler to gimbals housing, it has a rubber spot, see last picture, close up of this issue was working fine but defiantly wanted mention. Please see shipping options. Parts were removed from a 2003 4.3L V6, carburetors engine with alpha drive, and dry joint risers, standard cooling system. Some of the hoses still have readable part numbers, shown some close up pictures that.
