Where is the ac evaporator coil on a 1997 Oldsmobile 88

What is your question?

Looking to replace evap coil on Olds 88. 1997 yr. I'm a A/C tech old school residential /commercial. What I need help with is how much difficulty involved. As well as how many things I need to remove to get to it. I haven't confirmed the leak yet. How ever I have been over as much of the A/C lines, compressor, condesor etc as I can with a leak detector found none as of yet. Suspect evap leak. Any other common places leaks in this model car that u may know of that I can check please let me know. Thanks
