You would use your original condenser, unless you want to buy their new improved condenser. But, it should work with your condenser, and the rest of your original a/c parts. You'd need a new accumulator, which I think comes with the kit, along with hoses, compressor and compressor brackets. An Olds setup shouldn't look much different from the Pontiac setup. From what I see, I like the kit, and will get one when I work on my a/c again. I haven't had much luck keeping the rebuilt original compressors going for long, so I don't want to even put an original A-6 back on again. The more modern Sanden compressor is used on aftermarket a/c units, and I've put many of them in older cars, and have not had a failure. The Sanden is smaller and lighter, and can withstand high rpms.
