If we are talking about genuine factory air/cond (with the big black GM A6 compressor) the WB condenser is very different to HJ/X/Z.

Unless someone has a NOS one sitting around somewhere you won't find one.

They haven't been made in either OEM or aftermarket for many years. I sold my last one over 5 years ago.

There are plenty of other substitutes around, you just need to fabricate some mounts to suit & make some hose adaptors.
