Late 1963-1965 Corvair A6 compressors used a foil sticker to display model number, charge, and serial number. While these stickers have been accurately reproduced for non-Corvair A6 models, they aren’t correct for Corvair, due to the difference in Model number and charge.
Here is a photo of the reproduced sticker:
I, therefore, opted to keep the original foil sticker on the Glenn car’s A6, both for preservation and for accuracy. However, much of the sticker was in poor condition, the black having been rubbed away, etc:
After restoration of the compressor, the sticker was in even worse shape, having lost the lower right corner. I had used a marker to restore much of the missing black, but it wasn’t a great look:
Today I tried something new. I took one of my reproduction stickers and cut out the silver boxes for charge, model number, and serial number, then carefully positioned and stuck it on top of the existing, original sticker.
