Oh, I didn't realize you were trying to maintain the use of a spare holder. Still, the offer stands. I drafted up a quick example of what I could do to meet your needs...

It might be a good idea to affix the OEM wheel retainer to the new mount with some gasket maker, if the compressor dimensions allow for clearance at the gate cover. You may also have the option of mounting the spare in typical fashion and then mounting the compressor on top of that with a wingnut for easy removal... maybe.

I don't want to use 45deg straps to hold the cantilever up as the bracket would have to be wider than the compressor. Although very pretty if it were made of brass, a simple steel bracket will suffice.

This is a descrete job so all the hoses will be hidden as well as the wiring and switch. The plastic spare cover will be back in place.
