The kit I bought contained a pint of flush, a new oiled compressor w/clutch & pulley, a bottle of PAG-46 oil, a blue orifice tube (none of which are shown), the dye (1.5oz), the accumulator/drier, & the o-rings. I bought the red orifice tube & the adapter fittings because I'm converting an R12 system to R134a, instead of installing R12 parts. The evaporator core has been washed (hence the caps to keep water out of the lines), and the black accumulator strap has been modified to fit around this one's larger-than-stock lower diameter.

Factory R-134a service ports use rubber balls (which are easily cut) instead of Schrader valves; the conversion fittings are
F3AZ-19E762-A &
F3AZ-19E762-B.
A QUICKER & usually cheaper way to do this conversion is to find a '94-96 factory R134a system still sealed on a junk truck with the same engine as yours, and lift it out as a unit, including the underhood HVAC box, and the hood latch support bracket; and swap everything without opening either refrigerant system.
