Has anyone used the spare tire inflator kit that SVT developed for the Shelby GT500??
Basically they carried this over from the Ford GT program which didn't have a spare tire. It is a compressor that will plug into the lighter and can be used as a regular compressor or you can flip a portion of it and it will dispense fix-a-flat along with the air. They packaged it in a Styrofoam housing to fit in the spare tire well but it can be removed from that can be stowed separately.
They can be found on eBay for around $100 or through Ford Dealer and parts houses from a bit more:
