| I was pretty well versed on the a/c systems and their differences. You'll want to install all the components that were sent. I beleive the evaporator is different from the pre 94 in that there's only a thermal expansion valve involved. The pre 94 has a thermal expansion valve and a throttle suction valve which is how the system worked as climate control set-up vs select a setting. You'll need to change temp control module on the dash and the a/c ecu. The 134 system has some suttle differences but it's a pure 134 designed system. I beleive the condensor is different too in the density of the core and heat exchanger cooling fins. If you can get someone to copy the wire diagram and the a/c component section from a 95 manual and send it to you, you could compare with your 93 and check for the system differences.
