1992 300-E cabin filters .

[Bob G]

I want to change the cabin filters in my 1992 300-E. Were are they located and how do I install them? According to Fastlane if you look under Climate control you go down the list to ACC cabin filter partculate filter. Part# R2060-138299or R2060-53915.
I may be wrong about location but they do exist for my year . What is the proceedure and were are they located?
