Mine is a '93.
I bought a AC bypass pulley.
You will have to check to make sure its the right one but here is one from Rock Auto...

Everything just unbolts. I had to remove the grill to remove the condenser. When I removed the accumulator and hoses I taped over the ports to the evaporator. Personally I would leave the parts intact except for the compressor. I removed my old parts and by-passed the compressor til I figure out which AC system to put back. When you say everything I assume you would leave the evaporator since it is difficult to get to under the dash.
Is this your truck...
