The manifold set coming off the compressor is still available from GM. GM part number 25525272, Delco 15-3461. The line from the accumulator to the condensor is discontinued. This one is the same for all 86-87 Regals so you should have good luck finding a used one out there.
Do what ijames said, it will probably be cheaper, and faster. I was at the local hydraulics place yesterday to get new hoses for my turbo saver. About $40 cheaper than PTE, with much better hose, and they installed them.
