    I used the CU1518 from a 95 monte, 1.25" core.

    Stock lower rad hose doesn't fit well.

    71700 is the stock replacement lower rad hose for our cars.

    For the 95 monte core the fan shroud needs to be trimmed to sit flush again.

    my 2001 stock trans cooler fittings did not fit into that rad either.
