If the '93 is anything like my '86 underhood regarding the A/C system, it can still be effectively put together, but if your system was an original R12 system converted to R134a, there's a chance the line fittings won't be the same if you try and use new hardware.
I quickly learned that since I needed to replace my HVAC box under the dash and thought I'd be smart in replacing my evaporator core. All my old equipment used threaded fittings to join the lines together, but all the replacement stuff uses block fittings that utilize studs to mate them to the attaching point.
Now, going beyond that. The original style condensers usually used "back-in-the-day" (even if the 90s don't feel that long ago) usually weren't cross-flow designed and can be flushed if you do it properly. Same goes for the evaporator core. If you could clean the lines out and find a suitable drier that'll fit on the original lines, you could get away with replacing the compressor and adequately cleaning the entire system, then doing a proper vacuum and recharge.
If for whatever reason you do through the process of changing everything, we might be in the same boat. I'm currently in a position of figuring out how to appropriately work with the existing A/C switches on the system (capillary clutch cycle switch and high pressure switch) with more "modern" bits. Learning how to adapt the original equipment to available parts might prove invaluable going forwards.
