Hi all,
Decided to share my issue resolving to the lack of cab filter in 80 series. A/C dryer was packed by all kind of things and not working properly as windows started to get foggy, not enough air flow on air duct and weird smell.
Idea for modification was taken from eastern Europe LC enthusiasts forum and put to reality. This option allows to access cabin filter from under passenger leg room. Easy to clean up or replace.
Step 1:
Carefully masured and trimmed by Dremel or Proxon AC dryer box.
Step 2:
Heated by welding fan bottom plastic. Basically just straight 90° to avoid any air gaps.
Step 3:
Installed 1" wide thin steel profile on both sides and riveted (2 rivets on each side)
Step 4:
Thread rivet in bottom pieces of plastic and 1" aluminum angle drilled for holding up the filter. Plus made a little hole and leg for one side of that angle to sit in the frame.
Step 5:
Trimmed one side of cab filter and placed in.
Filter measurements: 157mm x 135mm + 6mm(1/4") foam weather strip on top.and bottom.
