When my '81 528I (since departed) A/C evaporator died at age 13, I got a used one from a '86 528E - the evap itself is the same size and of an improved design - more tube length and wider fin spacing for improved airflow. The only difference was the fittings on the IN and OUT pipes. The '86 was set up for "O" rings instead of the conical copper washers. I took the old evap and the new one to a machine shop and had them silver solder the old fittings to the new evap - worked great AND the A/C seemed to be better than it had ever been before.

I also believe that you could get a new stock evap for a LOT less than $500 from an outfit called ICE (I believe),
they advertise in the Roundel.
