The R134a specifc condenser is just half the story, you *need* to change to DUAL aux. fans for the proper airflow (don't forget the ballast resistor and a relay- almost double the current of the single aux. fan).
Also, you'll need to change the vertical bar where the horns mount as well as the powersteering cooler which takes a different route to clear the dual motors of the aux. fans.
The R134a condenser will need to have a custome hose made (about $75) due to different connectors as well as having a R134a service port installed.
I'll post pictures soon.
