Custom Fabrication - Rear enclosure

I am not quite sure how I am going to do this, but I sure am glad that these old cars have so much space in the trunk. I am going to custom build two enclosures to go behind the rear wheels that can serve the purpose of storage and hold my air compressor for my front airbags.

Here is a picture of the passenger side which will hold the air compressor.

Another nice thing about an old car is that you can use it literally as the notepad for your project.

Now all I have to do is figure out how I can make one without having to weld up all the individual pieces.
