Here is the missing piece
of your white overlays package!
This overlay is identical to the stock layout of
the HVAC controls on a 1986 Camaro with A/C. Download the
overlay and print it out on your choice of paper, cut out
the gray areas and glue it on top of the stock HVAC panel.
We suggest for the best result
that you take the file to a print shop and have them print
it out on a semi-gloss "sticker" type paper, so
that you can simply stick it on top of the stock HVAC panel.
