Answer
Hi
It is a HUGE job.
If you do not have decent mechanical ability, I would NOT recommend a do it yourselfer to attempt this.
That being said...
The entire instrument carrier/panel basically the entire dash.
The right fender/fender well. The outside A/C evap box.
I can send you the entire job, but it is about 150 steps that covers 3 sections in the service manual. You'll need A/C recovery and recharge.
Let me know....
