definately replace the drier and the orifice tube.
I switched over to r134 when replacing the compressor.
(i dont recommend 4 seasons rebuilts, btw...)
I used a special orifice for r134, and a new r134 pressure switch
(both available at o'riellys)
no need to change the condenser,but do blow out all the lines.

I was'nt real pleased with the results initially, so installed an electric fan with
relay to come on when the ac was on, and that made the difference.
