The condenser is going to be specific to your truck, just get a new one as it will fit, the one from the donor won't. Same goes for the Evaporator and the accumulator. Just get a new one for your year.
As for hoses, the ones on the 94 should fit as the Pancake (R4 I am assuming) was already used on these trucks up until 1991. If the system has been open, definitely replace the accumulator and replace the expansion tube also.
